how many prime positive integers are divisors of 555?
Answered by David Q/R
An obvious candidate is 5, so if you divide 555 by 5 you'll get 111. That's divisible by 3 (because the sum of the digits is divisible by 3, which is a useful quick check), so do that and you'll get 111/3 = 37. But 37 is a prime number, so you won't be able to find any more. So there should be just three, i.e. 3, 5 and 37.

When we find the prime factorization of 555, we end up with 3*5*37, which means we have 3 prime positive divisors.
