"Just click the green flag, and insert your number. All the factors will appear in the list. Anything above 50000 will take some time." - Original Project
Thanks to @DudmasterUltra and @AndieOldest for the original projects. I made it a bit faster by stopping the script once the factor it was checking got above the factored number divided by 2, and made it only check odd factors when the factored number was odd.
