alldivis.zip1k05-03-09File is not ratedFind All Divisors
This useful program is only 181 bytes, yet it will find every prime divisor of a number that you input. It will take up to 1 minute for numbers up to 8 digits, and about 10 seconds for numbers of 4 digits. This program will output its results on List4, so be sure not to store anything important there before running. Also, this program may take a while to run. Have fun!
aprime1.zip3k11-09-04File is not ratedAPRIME1,2,8&9
APRIME1: This prime factor program is the best compromise between speed and size. With only 146 bytes it tells you that 333667 is a prime in just a little more than two seconds, on an 83 Plus. APRIME2: This prime checker uses a list of 48 numbers, ( LP ) which you need to install on your calculator. It is really fast with smaller numbers, and a big prime like 10566779 is confirmed in just 8 seconds! APRIME8: This program is the same as APRIME1, except that it shows the factors with their power. You never risk running out of screen with this program. APRIME9: This program is aimed for the really big primes. It uses two lists, LP and LQ, which you need to install. The later has 480 numbers in it, and takes up more than 4000 bytes.
aprimedivisor2.zip1k10-07-28File is not ratedAPRIME+DIVISOR2
APRIME: This little program ( 117 bytes ), finds the prime factors of a positive integer, faster than most other programs of this kind, and it does so without skipping any END-commands. A great advantage, since skipping those consumes a lot of memory. DIVISOR2: This program finds the divisors in a positive integer. It does so without skipping any END-commands. It is very fast compared to the ordinary program of this kind, since it is a converted prime factor program. Only 172 bytes.
aprime.zip1k05-11-26File is not ratedAPRIME v.2.1
APRIME is a prime number finder. It is very small and very easy to run. Optimized for SAT I Math and SAT II Math IIC. I've tested it on both tests, and my prime number finder program is better than others because it is small and easy to run. So try it out today for that test.
bprime.zip1k00-08-29File is not ratedPrime Factor v1.0
Highly optimized program will factor a number that you input. Amazing speed for BASIC!
cheat3.8xg.zip144k11-01-19File rated 7.28Cheater v3.0
This is one of the most complete suites of homework help functions in existence, and it's all packed in one program (with an assembly subprogram for some of the chemistry functions). Featuring an easy-to-use menu system, it packs dozens of extremely useful algebra, geometry, calculus, chemistry, and physics functions for middle school, high school and even college courses. Includes 18 different area, volume, and surface area solvers for geometry students, a list of essential trigonometric identities, and many intuitive calculators for many other topics, such as a complete triangle solver. More general features include 326 different unit conversions (in an extremely simple scrollable graphical interface) and many other essential features, such as chemical equation balancing and formula interpreting. Check out the screenshots; you'll be amazed.
curtsfactor.zip587k20-02-03File is not ratedFACTOR
This program finds the integer solutions to the equation of a hyperbola to find divisors/factors of any integer. This update only corrects typos in the documentation and additional information.
divisor3.zip1k10-07-29File is not ratedDIVISOR3&APRIME2
DIVISOR3:This program finds all the divisors of a positive integer. It is extremely fast compared with other programs of this kind. For example: 1 000 000 is handled in 5 seconds on an 83Plus, and only 2 seconds on an 84 or 83P SE! Compare this with your present program and you'll see why you rather want this program on your calc. APRIME2: This program finds the prime factors of a positive integer. It uses a list ( list N ), that you must install on your calc. It is extremely fast since it does not divide with numbers that have a factor 2, 3, 5, or 7.
divisor4.zip1k10-08-04File is not ratedDIVISOR4&5
DIVISOR4: This program finds the divisors of a positive rational number. For example: 144, 30030, 4.55 and/or 2.36. In case it's a decimal number, you get all the divisors of the numerator divided by the denominator. Look at the screenshots. DIVISOR5: This program finds the divisors of a rational number, positive or negative. It has a much bigger capacity than the above program. It uses strings for the larger rational numbers. To convert the numbers, it has a subroutene: NBR2STR, written by Nick King.

divisors.zip2k10-08-12File is not ratedTwo Divisor Programs
These programs finds all the divisors of a positive integer, or as you would say: factors, wich is not a correct denomination. There is also a text version of one of the programs in the file. They are converted prime factor programs, and as such extremely fast, compared with the ordinary programs of this type.
divisor.zip1k03-08-26File is not ratedDIVISOR
This program computes all the divisors of a natural number with unsurpassable speed. At only 64 bytes it's a truly elegant program. The other programs don't even come close to matching it.
divis.zip1k04-12-03File is not ratedDivis
Enter a number, and it will tell you all the factors. If you enter 98 it will give you 1, 2, 7, 14, and 49. If the number is prime it will say so.

mcfactor.zip1k05-08-10File is not ratedFactor
This is a great program for school. It figures out the factors of numbers. It shows you the ones it figures out as it goes along and then lets you scroll thorough them when it's done. Just don't put in huge numbers, like 500, or it will take forever!
modfactr.zip317k20-02-03File is not ratedModular Factoring 1
This program finds the factors of any positive integer. It takes about 10 seconds to determine that 1,000,003 is prime, and about 3 seconds to find the factors of 1,000,009. MODFACTR is based on my earlier program FACTOR (at https://www.ticalc.org/archives/files/fileinfo/471/47178.html )
modfac.zip317k20-02-03File is not ratedModular Factoring 2
This program finds the factors of any positive integer. It takes about 7 seconds to determine that 1,000,003 is prime, and about 2 seconds to find the factors of 1,000,009. MODFACT is based on my earlier program FACTOR (at https://www.ticalc.org/archives/files/fileinfo/471/47178.html )

numfact.zip1k04-02-17File is not ratedNumber Factorer
Really useful number factoring program.
pd.zip1k04-08-19File is not ratedPrime Decomposition
Using a combination of divisibility tests and methods inspired by fermat factorization, this program can find the prime decomposition of a number with remarkable speed and efficiency. Fermat factorization is usefull for factoring large numbers that are known to be the product of two primes relativly close to the square root. For example, this program factors 12240467203 into 100003*122401 in around 10sec. This updated version is more memory efficient than the original.
pfactors.zip1k01-08-05File is not ratedPrime Factors

pfact.zip1k05-07-23File is not ratedPrime Factorization 1.3
PlanMath prime factorization program by Planetar.
pf.zip1k00-10-13File is not ratedPrime Numbers and Prime Factorization
prgmPRIME creates a list of 999 prime numbers using prgmPRIME2 as a subprogram. This takes around 25 minutes. prgmFACTORS executes prime factorization using the list (expressions are okay); it shows the value of the number entered.
png.zip3k03-08-04File is not ratedPrime Number Generator
The program will test a nubmer for being prime or generate a list of primes up to 999 primes. Will test prime numbers 2 to 999999937.
pnu.zip1k12-02-08File is not ratedPrime Number Utility
The Prime Number Utility has two main parts: The Prime Number Tester and the Prime Number Lister. The Prime Number Tester allows you to enter in any number, and it will tell you whether that number is prime or not. The time it takes depends on how big the number is. You then have the option to factorise that number or not. The factorising algorithm isn't particularly fast, but it does work, if you are willing to wait for it. I wouldn't recommend trying to factorise anything over 3 digits, beacause it will take a long time and most likely run out of memory. The Prime Number Lister allows you to create a list of prime numbers up to a number that you specify. The only limit on how many primes you can generate is the amount of memory your calculator has. The Lister will also store the primes into a list for you to work with. IMPORTANT: I have just fixed a glitch where it would think that composite numbers like 17711 (89x199) are prime. I have also fixed another glitch where if the lower factor of a number is an even number greater than two, the factor and its pair would not appear in the list of factors. If you are not using the latest version, please update!
porc.zip1k02-10-23File is not ratedPorc
PORC is a program that you can use to test and see whether a number is prime or composite. The only downfall to this program is that the larger your number is, especially if it is prime, it takes the calculator longer to tell you whether the number is prime or composite. This program however works really well with the numbers that I use!
posfacto.zip4k04-02-09File is not ratedPossible Factors
This program show all factors to get the number you put in. It display, too, if it's a prime. POSFACTO is only 237 big.
ppt.zip1k04-08-20File is not ratedProbabilistic Primality Test
This program is based on Fermat's theorem. You enter a number P and a base A such that (P,A)=1. If P fails for any base than it is composite. If P passes than it is probably prime. A prime will pass for all bases. The program can handle numbers up to around 2000000. It can prove 2029039=1013*2003 is composite in less than 3sec! Under 200 bytes
prfactor.zip1k05-09-08File is not ratedPrimeFactor
This was so fun to make. This will tell you the prime factors of any number you put in. Obvious, big numbers [telephone numbers.] will take a LONG time, but smaller numbers [and some larger numbers.] take about 10 seconds. Email me if you have any problems.
primality.zip7k05-12-01File is not ratedPrimality Tester
My first program, it checks whether or not a number is prime or composite; in other words, its primality.
prime_13.zip1k09-06-10File is not ratedAmazing Prime Number Generator
This amazing machine will generate a list of prime numbers faster than any other program on the market. It's a great way to pass countless hours in math class! If you don't believe me...try it for yourself!!! Unlike other programs, this one has been tested extensively and is made for convenience.

prime83.zip1k00-06-08File is not ratedPrime Number Tester v8.85
ATTENTION ALL ALGEBRA STUDENTS!!! This program is self explaintory. You enter in a number and it determines if a number is prime or not. Then finds the two simpliest numbers (e.g. the simpliest multiples of 150 are 10 and 15; the simpliest multiples of 300 are 15 and 20; a simpliest multipleis the smallest sum of two multiples; the simpliest multiple of 100 is 10 and 10. It is not 1 and 100 or 2 and 50 etc because 10+10=20, 1+100=101, 2+50=52; 20 is the lowest number) that multiply to the inputted number. It tells the time remaining when it is trying to find the multiples, and it also tells you the numbers that divide evenly into the number that are under 20. DOWNLOAD!!! BUG FREE!!!
primea6.zip1k12-01-31File is not ratedA6PRIME
This is the best prime checker I have made. It is extremely fast if the number has two big prime factors, and very fast in every other way. Only 240 bytes.
primeadv.zip1k10-04-04File is not ratedPrime Advanced
Check if a number is prime. This is generation 2 prime checking program. It utilizes multi-threading and can check all numbers in range in no more than a minute (tested on TI-84 Plus SE), a bit more for numbers closer to the large end of the range. This is one of the fastest brute force prime checkers programmed using TI-Basic. This is the export version and more informative during the processing, it is slightly slower than the competition version but much faster than the generation 1 checkers.
primebp.zip2k11-10-06File is not ratedBrent-Pollard Rho Algorithm
APRIMEBP: This is the Brent-Pollard rho algorithm. It is a monte carlo method for factoring composite numbers. Its speed varies because some of the constants are randomized, so the time differs for the same number. In average though, it is a very fast algorithm. It will only give you one factor, which won't always be the smallest one. APRIMEP: This is Pollards monte carlo method which Brent improved upon. It's a lot simpler, but a bit slower. Brent says that he's algorithm is about 24% faster, and that seems correct. APRIMBPT: This is a simplification of Brent's algorithm for which I am responsible. It is not as fast, but it seems to fail less often, ( i.e. retreat to using Pollard's algorithm ).
primec1.zip1k11-04-02File is not ratedPrimeC1
This program is a version of PrimeC that doesn't skip END-commands, wich is useful when you don't have much memory left. Skipping those will consume a lot of memory: up to more than 100 bytes for each one. Tricky numbers will then give you an ERR: MEMORY message, and hence stop your calculation. Not so with this version. You need to run PRCINST first.
primecalc.zip1k13-04-12File is not ratedPrimeCalc
it will just calculate all Primes until you end it!

Make Sure I Receive Credit!-
primechk.zip1k06-09-08File is not ratedPrime Checker
This is the fastest prime checker available for the 83. I've checked the rest, and this one beats them all. The key is that it doesn't check if numbers like 9, 15, 21, etc. divide the number in question. This program ends up checking 1/3 fewer possible divisors compared to most other programs. If the number is composite, it lists a divisor.
primec.zip4k11-04-02File is not ratedPrimeC,PrimeC2&PrimeC3
Three of the fastest prime factor programs for the 83/84 Plus. They use lists with 48 numbers to speed up the process. The later ones also uses another list with eight numbers, to search for numbers within the larger list.

primeq.zip2k04-12-01File is not ratedPrimeQ
Based on the Rabin-Miller probabilistic primality test this remarkable program takes primality testing on the TI-83+ to the next level. For large numbers, this program finds primes over 20 times faster than the fastest trial division programs ( e.g. - primec.zip). "Probabilistic" means the program declares a prime with high certainty but not quite 100% due to the existence of composite numbers known as strong pseudoprimes. However, the program will continue conducting tests, approaching 100% ever closer, until a primality proof is established. For large numbers, such a proof is still up to 6 times faster than the fastest trial division programs. As an example, 1013279437 is PROVED to be prime in 16 seconds! Under 400 bytes!
primer4.zip1k01-01-06File is not ratedPrime Number Tester v2.0

This tests for prime numbers, it is the fastest I've ever seen for the calculator.
primferm.zip2k19-08-17File is not ratedPrimes with Fermat
This program utilizes the fact that if you have two positive numbers A and B, and sqrt(B^2 - A) is a positive integer, then B - sqrt(B^2 - A) and B + sqrt(B^2 - A) are factors in A. If A has two factors, ( which may or may not be prime numbers ), B is ( F1 + F2)/2, where F1 is the smallest factor. This is known as Fermats factorisation method. So B is always bigger than or equal to sqrt A and smaller than or equal to F2. Therefore this method is extremely fast when the two factors are of similar size. However it is just as slow a way, when there is a big difference in size, compared to an ordinary program, and so this program also features a very fast conventional program, which counts up much faster than the ordinary one. Enclosed is a link to a Wikipedia article on the subject.

prlist1.zip2k11-01-09File is not ratedAPRLIST1,2&3
These three programs find the prime numbers in an interval of your choice. The first two consist of two programs each, one for short intervals, and another for longer ones. This makes them very fast for their purpose. The third program uses a list ( LP ), with the prime numbers between 1 and 1000. ( You need to install it on your calc. for the program to work. ) It has three subprograms. One that uses the list, another for longer intervals beyond the list, and a third for shorter intervals, beyond the list.
prlist2.zip2k11-05-13File is not ratedAPRLIST4,5,6,7&8
These programs are built around another concept than my programs in prlist1.zip. They are very compact and fast. Number 4 and 6 give the prime numbers from 2 and onto a number you enter. Number 5 and 7 give the primes within an interval that you specify. Number 8 consists of two programs, one for longer intervals below 10 000, and one for shorter intervals and above 10 000.
