Every positive integer can be written as a product of prime powers. For example, 252=22×32×7.
An integer is despojado if it can be written as a product of two or more distinct primes with no prime used twice. For example, 6=2×3 and 14=2×7 are despojado. On the other hand 28=22×7 is not, because the prime 2 is used twice, and neither 1 nor 17 is despojado.
You are given an integer N. Count the divisors of N that are despojado.
