If you know the prime factorization of a number, you can tell how many factors it has.
Write the prime factorization with exponents. Add 1 to each exponent. (Numbers without exponents actually have the exponent 1.) Multiply them together. That will be the number of factors.
10 = 2 x 5 = 21 x 51
2 x 2 = 4
10 has four factors.
