Developer Description

"A factorization and prime number program"

Prime Factors is a Windows program to find factors of numbers up to 2,147,483,646 and to find primes, pairs of primes and Palmen colors of numbers. Or in more detail, Prime Factors may be used: (1) to get the prime decomposition of all numbers in a range of numbers, (2) to get all factors of a single number or all factors of all numbers in a range, (3) to find only the prime numbers in a range of numbers, (4) to find pairs of prime numbers (e.g. 107 and 109) in a certain range, (5) to count (without displaying) the prime numbers in a range of numbers, (6) to find the Palmen color of a number or the colors of a range of numbers and (7) to generate the Ulam prime number spiral. In addition a "filter" condition may be set to allow examination of numbers with a constant offset from an arithmetical or a geometrical progression, e.g., just those numbers of the form 7*n - 12 or 10n + 2.
