If you know the prime factorization of a number, you can find out the total number of factors.
Example: 210
2^1 x 3^1 x 5^1 x 7^1 = 210
Add one to the exponents and multiply them.
2 x 2 x 2 x 2 = 16, the total number of factors.
You know that 1, 2, 3, 5, and 7 are factors. You need three more to get halfway.
2 x 3 = 6
2 x 5 = 10
2 x 7 = 14
Divide all those numbers into 210.
(210,1)(105,2)(70,3)(42,5)(35,6)(30,7)(21,10)(15,14)
