DIVIDERS LIST OF AN INTEGER File(s) : divlist.9xg or divlist.89g Type : Maths, TI-BASIC Author : Rémi Denis-Courmont e-mail : rdenis@multimania.com Size : 0,8 Kbyte Plateform : TI-92(+) and TI-89 - any language Description: These programs determine the positive integer dividers list of a positive integer, and can check whether a number is a perfect number or not. Date : last-updated on September 23th 2001. Version : 1.1 Installing ----------- Send either divlist.89g to your TI-89, or divlist.9xg to your TI-92(+). Usage ------ In order to get the dividers list of an integer, type: divlist(n) where n is the integer. e.g.: divlist(28) returns: {1 2 4 7 14 28} So as to display the sorted diviers list, type: divl(n) where n is the integer, the dividers of which you want to display. To determine whether or not n is a perfect number, type: isperfct(n) which returns either true or false. A number N is perfect if and only if the sum of its dividers (apart from N itself, of course) is equal to N. So, 6 and 28 are the littlest 2 perfect numbers, as: 1+2+3=6 1+2+4+7+14=28 Liability ---------- These files are provided "as is", without any warranty of any kind.
