-
- - factors any number from 1 to 10 Trillion.
-
- - finds the Greatest Common Factor (GCF) of up to 10 numbers
- from 1 to 10 Trillion.
-
- - finds the Least Common Multiple (LCM) of up to 10 numbers
- from 1 to 10 Trillion.
-
- In short Prime does things that can be done on a calculator but
- not with out a lot of button pushing.
-
- Menu options

- Desk - Prime is written and compiled in GFA BASIC 3.0
-
- Find - Enter any range, but the higher the numbers the

- To interrupt press Control, Shift, Alternate.
-
- Playback - Plays back found or loaded primes.
-
- Print - Prints primes.
-
- Load - Loads primes from disk.
-
- Save - If saved with .PRI file will be shown in the

-
- New file - Saves primes to a new file or
- over writes an old one.
-
- Old file - Adds primes to the end of an existing
- file. A large list of primes can be
- made this way even with limited memory.
-
- Prime factor - Breaks a number down to it's prime factors.
- 100 = 2 X 2 X 5 X 5
- 13 = 13 X 1
-
- Factor - Finds the factors of a number.
- 100 = 1 X 100, 2 X 50, 4 X 25, 5 X 20, 10 X 10
- 13 = 1 X 13
-
