This software allows users to find prime numbers and pairs of primes, decompose numbers into their prime constituents, and find all factors of any positive integer up to 2,147,483,645. It also includes features such as plotting of Erdos-Kac and Palmen Color histograms.

This software offers several features that make it a valuable tool for mathematicians and researchers alike. It can be used to get the prime decomposition of all numbers in a range of numbers, as well as to get all factors of a single number or all factors of all numbers in a range.
Another great feature is the ability to find only the prime numbers in a range of numbers. Moreover, one can find pairs of prime numbers in a certain range or count (without displaying) the prime numbers in a range of numbers. The program can even find Fermat and Mersenne primes less than 2, 147, 483, 647, and discover the Palmen color of a number or the colors of a range of numbers.
The software program is not limited to these features though - one can set a "filter" condition to allow examination of numbers with a constant offset from an arithmetical or a geometrical progression. For instance, it does not have to examine all the numbers but just those numbers of the form 7*n - 12 or 10n + 2.
Overall, Factorizer is an outstanding and highly efficient software program that can generate a treasure trove of numerical data quickly and accurately.
