Try and factor something really hard, like N=6 or ...maybe 15.
First time I read this I thought it said "N= 187!" -- the product of the integers from 1 to 187.

I can factor 187 mentally (2 doesn't divide it, 3 doesn't divide it, 5 doesn't divide it, 7 doesn't divide it, 11, -- divides it!) , and anyone can factor 187! with pencil and paper, if they can reckon the primes up to 187.
