This is similar to the last project I done "Factors finder" but this project doesn't say the factor but factorise the entered number. There are two output:- one is the simpler form used in most mathematical calculations and second one is the expanded form.
This project is still in testing :) this project works good till 1000000000000000 (10^15) but this doesn't mean it doesn't work after 10^15 but testing have not been done after that. the speed doesn't depend on the number of digit, but the number itself.
