math, please help
posted by lily on .
1)List all #s less than 100 with exactly 5 factors.
For this I got 16 , 36, 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.
Are you including 1 and the number itself, or not? Either way, 36 has more than five factors: I can think of 2, 3, 4, 6, 9, 12 and 18. (Or do you mean prime factors?)
I am including 1 and the # itself, and you are right, 36 is not one of the answers. thank you for the correction, but i still need help with the second problem
