1)List all #s less than 100 with exactly 5 factors.
For this I got 16 , 64, and 81.
2)Find the next 2 #s, each greater than 100, that have exactly 5 factors.
This is the problem I am having trouble with.

2*2*2*2=16, which is only 4 factors. The factors do not include 1. 32 would have 5 factors. 64 has 6, and 81 has 4. You need to be aware that the factors don not need to be the same numerical value. For example, 2*2*2*2*3= 48.
I hope this helps. Thanks for asking.
