The basic idea of Strassen's factorization method is that if you have the product f i of a consecutive set of integers modulo the number to be factored n, and that set of integers contains one the factors of n, then g c d ( f i, n) will be greater than unity. The trick then is to compute f i for non-overlapping sets of ...
