 | ephi.zip | 4k | 11-10-26 |  | Euler's Totient (Phi) Function
Function that returns the number of integers less than the integer input that are coprime (relatively prime) to the input. Useful in number theory when working with modular arithmetic and congruences of powers. |
| nxtprime.zip | 7k | 10-12-06 | | Next Prime
A powerful function that returns the smallest prime greater than the number provided as an argument. This program works very quickly considering it uses merely 101 bytes of memory and is far better than manually testing every odd number greater than a given one. |
 | primetest.zip | 1k | 10-10-06 | | Prime Find
Find prime numbers greater than a specified value. |
| conicompletesq.zip | 1k | 09-09-06 | | Conic Completing Square
many conic equations are entered in the form ax^2+bx+cy^2+dy+e=0. this program manipulates the equation in the form that may look like(x+1)/3 + (y-4)/2 |
 | rprime.zip | 11k | 06-12-30 | | Relatively Prime
This is a very small program that tells you if two numbers are relatively prime or not. Great for math class! |
| factors.zip | 1k | 06-11-20 | | Factors
This program calculates all the factors of a number (not like the built-in function "factor(n)", which just finds the prime factors). |
| primt.zip | 4k | 05-09-25 | | Lucas and Perrin Prime Tests v1.0
Two probablistic prime tests involving the Lucas and Perrin Sequences. They are implemented by using modular exponentiation with the Q-Matrix method for time-efficient results. Functions return 'true' or 'false' for a given integer argument. Can test 64-digit integers in just under a minute. |
| diviseurs.zip | 1k | 05-06-11 | | Diviseurs
A very powerful program which find all positive dividers of a number. Un programme très puissant qui trouve tous les diviseurs d'un nombre. |
| primefunctions.zip | 1k | 03-12-28 | | Prime Functions
Here in this group file are some prime number functions based on the built in prime number test. There are no prime functions, built in, only the tester. The primary prime function returns which prime number you want, 2 being the first. Relatively fast. |
| factor3.zip | 27k | 03-07-28 | | 0Factor
Hopefully the last release of the well balanced factor program (speed and size) for the 89. This latest release was made when the author realized how much faster the fpart() function was that modulus...increasing factor speed by 1.5-3 times... A Pyrosoft Production |
| primes89_2.zip | 5k | 03-07-17 | | Prime Factoror
This factors ANY # into primes, with negative and decimal support (1st time ever). |
| mgcflcm.zip | 1k | 03-07-09 | | MGCFLCM
Contains two functions: mgcf and mlcm. mgcf computes the greatest common factor of a list (of any number of integers). mlcm computes the least common multiple of a list (of any number of integers). There also is no error when something other than a list is passed; the function will just return 0. |
| factall.zip | 4k | 03-06-24 | | FactAll - Quickly Find All Factors
factall() is a TI-89 basic program that finds all factors of an integer. The built-in factor() function only finds prime factors; factall() uses this function to compute additional factors (including composite factors). Useful on the SAT. |
| factor.zip | 2k | 03-06-18 | | 0Factor
This is a port of the 86 factoring program. This tiny program produces fast, accurate results with great efficiency. It doesnt have any annoying menus for something so simple. |
| prime89a.zip | 1k | 03-03-18 | | a prime number solver
this program, made by michael youssef, finds prime numbers. it is very very very useful. you dont know how often you need it. email me at killajoy6666@charter.net |
| primes_1_100000.zip | 118k | 03-03-10 | | Primes: 1 - 1,000,000
These lists contain all the primes, 1 to 1,000,000. Each of the 20 lists contains all the primes in each set of 50,000. |
| sumfact.89p | 1k | 02-04-22 | | Sumfact
This is a cool little program that lets you input a number and it will give you the sum of all its whole number factors. |
| findfact.zip | 1k | 01-12-22 | | findfact
Will find all factors of the number entered into the parenthesis. Works like a function. All factors are stored in a list for later viewing. |
| divlist.zip | 4k | 01-12-16 | | Dividers list/liste des diviseurs
Determines the positive integer dividers list, and checks whether a number is perfect |
| premier.zip | 1k | 01-06-01 | | Premier
list prime numbers |
| diviseur.zip | 1k | 01-06-01 | | Diviseur
Same functions as factor([integer]) but programmed in BASIC ;-) |
| premnbr.zip | 7k | 00-10-13 | | Prime Numbers (French)
programes on the prime numbers |
| bprime.zip | 1k | 00-08-29 | | Prime Factor v1.0
Highly optimized program will factor a number that you input. Amazing speed for BASIC! |
| primes.zip | 22k | 00-08-23 | | The First 14,423 Prime Numbers
This is a list of the first 14,423 prime numbers |
| primefinder.zip | 1k | 00-06-13 | | Prime Number Finder v1.0
Generates a list of the prime numbers found within a specified interval. Very fast. |
| primegen.zip | 1k | 00-04-13 | | Prime Number Tester
This program tests a number for primality, then displays its factors if it is prime |
| primfact.zip | 1k | 99-12-25 | | PrimFact89
A very small, very easy program that will find the prime factorization of every number. |
| divise.zip | 1k | 99-12-07 | | Diviseurs Communs
Programme determinant le diviseur communs de 2 nombres et cela de façon detaillé (il n'y a plus qu'a recopier sur la copie), ce programme permet aussi de connaitre tous les diviseurs d'un nombre. |
| prime.zip | 1k | 98-10-16 | | Prime Number Program
Determines whether a whole number is prime or composite and lists its factors. |
