WHOLE NUMBERS I MEANT
2006-10-08 07:28:33 · update #1
Lots! Just take 3 or 4 prime numbers (not including 1) and take their cube and, voila, you have numbers that have exactly 3 or 4 divisors.
(I'm not sure 1 and the number itself count, as shown in answer #1 above, but you should check with your teacher to see if s/he wants you to include 1 and the number itself as the divisors.)

Some numbers that have only 3 or 4 divisers are 4, 6, 8, 9, 10. There are ,ore than that. Its just that you have to find the factors of each number. All the numbers that I listed have 3 0r 4 divisers.

3 divisors: The square of any prime:
2,4,9, etc.
4 divisors: Any number which is the product of 2 primes
will work: 6, 10, 14, etc. The cube of any prime
will also work: 8, 27, 125, etc. .
