600851475143 = 71* 839 * 1471 * 6857

It's factors are 1, 71, 839, 1471, 6857, 59569, 104441, 486847, 1234169, 5753023, 10086647, 87625999, 408464633, 716151937, 8462696833,  and 600851475143

I wrote a stack that will do this for any number whose largest prime factor is around 100,000,000 or which is a prime up to about the square of that.  This one took more time to display the results than to calculate them.
