Ooops, I did it again!

Obviously you're not living right. (Special note: this already factored for me, no need to waste any time on it.)
Code:

BTW, for those of you following along at home:
Code:
prp32 factor: 14202981758988057504195921169853
prp50 factor: 14758366028944853574664033531885329816029769322469
Maybe there's something special about my small numbers!

Shoot.....only a 1/32768 chance. Not quite enough to go play the lottery yet! (Or am I off by a factor of 2?)
