The only numbers which have exactly three factors are perfect squares of prime numbers. That only gives us two results:

5^2 = 25

7^2 = 49

The squares of any other prime numbers are either too small or too large to have two digits. (The next smaller Prime number is 3, and the next larger prime number is 11.)
