    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Yes, you said that already.

    What have you written so far?

    Find a prime number,
    work out whether it is a divisor of 'n' or not,
    repeat.

    OR
    Work out a divisor for 'n',
    check whether it is prime or not,
    repeat.

    What's so hard?

    I made a program that does this to an extent, too bad you haven't shown any code that we could help you with. Otherwise I could start pointing you in a certain direction.

    EDIT: ok I'll give some help. My algorithm uses Salem's first method.

    Ha. You think, from the answers so far, this guy is actually going to bother finding out what Salem's first method is about? Or even to write a single line of code? He just wants teh codez.
