Probabilistic Non-Negative Matrix Factorization with Binary

WebAug 2, 2016 · 1 I recently figured out my own algorithm to factorize a number given we know it has 2 distinct prime factors. Let: a b = c Where, a < b Then it isn't difficult to show that: c! c a = integer In fact, c! c a + 1 ≠ integer So the idea is to first asymptotically calculate c! and then keep dividing by c until one does not get an integer anymore.
