CFB Primes is an optimised PalmOS program which can find the prime factors and closest primes of any integer up to one billion (US) in a few seconds or less. The standard edit menu allows you to make use of the results in other applications.

A program to find prime numbers and pairs of primes, to decompose numbers into their prime constituents, to find all factors of any positive integer up to 2, 147, 483, 645, and to plot Erdos-Kac and Palmen Color histograms.

calculates the prime numbers 1..N, tells you if N is prime etc. Prints tables of primes. Computes the prime just below or above N. calculates the prime numbers 1..N, tells you if N is prime etc.

The Prime Number Spiral (a.k.a. the Ulam Spiral) is formed by marking the prime numbers in a spiral arrangement of the natural numbers. This is software is for exploring the Prime Number Spiral.

Calculates the factors of any number with a single click. Single application file allows simple installing and uninstalling.

Calculates the prime numbers between two limits. It uses a deterministic test and uses the Sieve of Eratophenes logic. Single application file allows simple installing and uninstalling.

Finds the prime factors of positive integers, solves triangles and circles problems, manipulates complex numbers, does base conversions. Results can be saved or printed. Includes a help file with instructions, example and methodology.
