Hermetic Systems

Windows software to find all factors of numbers,
prime numbers and pairs of primes (and more)

1. Introduction

Factorizer may be used to: 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. Here is a typical screenshot:

Compatible with Windows 7 The text in the output window can be edited, so you can remove unwanted output and add your own comments before copying to the clipboard for transfer to another program such as a text editor.

Examples of the use of the program are given below, first without a filter condition in effect, then with various filters in effect.

Following accepted mathematical convention, the number 1 is not held to be a prime number.

The remainder of the user manual is in the following sections:
