Factorizer 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, Factorizer 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 Fermat and Mersenne primes < 2,147,483,647
(7) to find the Palmen color of a number or the colors
of a range of numbers.

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.
