About this tool

What does Prime Number Generator do?

Generate prime numbers up to a chosen limit. The workspace keeps the input and result together, making it easy to check the change before you use it elsewhere.

For example, you can generate prime numbers up to a chosen limit before testing a layout with varied data.

What you can control

Prime Number Generator stays deliberately simple: add the maximum, run the tool, and review the result.

How to use Prime Number Generator

  1. 1

    Enter the maximum carefully and check that the unit or format is correct.

  2. 2

    Review the maximum and correct anything you do not want carried into the result.

  3. 3

    Run Prime Number Generator, check the answer against your inputs, and copy the result if you need it elsewhere.

Tips for a better result

  • Save the Prime Number Generator settings with any sample that needs to be recreated later.
