Example Input: 3 ... Web19 dec. 2012 · 2 Answers. Sorted by: 2. The basic answer is to calculate the factorization of each number of interest, then use that to calculate the number of divisors: if the factorization is a^w * b^x * c^y * d^z then the number of divisors is (w+1) * (x+1) * (y+1) * (z+1). You can find the factorization in a couple of ways.
