Before using the Program Library Be sure to check how many bytes of unused memory is remain-
ing before attempting to perform any programming.
This Program Library is divided into two sections: a numeric
calculation section and a graphics section. Programs in thenumeric calculation section produce results only, while graphics
programs use the entire display area for graphing. Also note
that calculations within graphics programs do not use the
multiplication sign () wherever it can be dropped (i.e. in front of
open parenthesis).

PROGRAM SHEET
Program forPrime Factor Analysis
Description
Produces prime factors of arbitrary positive integers
For 1 < m< 1010
Prime numbers are produced from the lowest value first. END is displayed at the
end of the program.
(Overview)
mis divided by 2 and by all successive odd numbers (d= 3, 5, 7, 9, 11, 13, ....) to
check for divisibility.
Where dis a prime factor, mi= mi1/dis assumed, and division is repeated untilmi+ 1

PROGRAM SHEET
Program for
Greatest Common Measure
Description
Euclidean general division is used to determine the greatest common measure for two
interers aandb.For |a|, |b| < 109, positive values are taken as < 1010
(Overview)
n0 =max(|a|, |b|)n1 = min (|a|, |b|)
nk2nk = nk2 nk1nk1
k= 2, 3....
If nk= 0, then the greatest common measure (c) will be nk1.
Example [1] [2] [3]
When a= 238 a= 23345 a= 522952b= 374 b= 9135 b= 3208137866
c= 34 c= 1015 c= 998
