| Name: Mary Lou Who is asking: Parent Level of the question: Secondary Question: My daughter had a problem of the week problem last quarter that we never did solve! Show the 10 numbers with exactly 5 divisors. |

Hi Mary Lou, Divisors come in pairs. For example consider 12
Thus 12 has 6 divisors, 1, 2, 3, 4, 6 and 12. How can a number have an odd number of divisors? Penny |
12 |
