Factorizer

Factorizer is a straightforward piece of software that allows you to find prime numbers, pairs of prime numbers and all factors of numbers, with no more than a few mouse clicks.

This utility can be used for a broad range of tasks, for example, for finding the Palmen colors of one or multiple numbers, as well as for finding the Fermat and Mersenne primes. Even simpler, it can be used to count the prime numbers in any range of values, to find pairs of prime numbers, and to discover all factors of a single number or all factors of multiple numbers within a range.

The application can be deployed in a matter of seconds and without much effort thanks to a typical installer. The application sports a compact and unresizable main window that may look and feel a bit crowded, especially since it cannot be resized.

Nevertheless, since all the features are right on display, you should not encounter any issues working with the app. Simply add enter the start and end numbers, choose the operation from the provided list (located the left-side of the main window) and hit the "Compute" button. The results will be almost immediately displayed on the dedicated panel from the right side of the main window.

Please take into account that the application also provides you with a way to filter the results. For example, you can choose to allow the examination of numbers with a constant offset from arithmetical or geometrical progressions. As expected, you can easily copy the results to your computer's clipboard using the designated button. You can save the current state which allows you to restore the results with only a mouse click later on.

Even though it is slightly outdated (regarding looks, anyway), Factorizer is a very efficient application that allows you to extract and find prime numbers, or pairs of prime numbers with the least amount of effort.
