The Factorizer Utility
This utility is designed to factor positive whole (integer) numbers.
It identifies prime numbers.

To use this utility:
Enter a positive whole number in one or both of the text boxes on the left, as is shown in the
example above.
Press the Factor button.
If you want to copy the resulting factors to the clipboard, simply select the desired resulting factors,
right click on the text box containing those factors, and then select copy. At that point you can paste
it into a Numera Expressions or Function Grapher document or a word processor etc.
This utility is designed to "stay on top" while you work and you can multiple instances of it.
It can also be minimized and restored when needed.
