Well, If we looked at this way: (224) = 16777216, so this number has exactly 24 factors. (324) = 282429536481, so this number has exactly 24 factors. (510)(210)(34) = 810000000000, so this number has exactly 24 factors.
A number that has exactly two (positive) factors is called a prime number. For instance, the only factors of 7 are 1 and 7.
The number 1 or a factor.
The first number to have exactly 10 divisors is 48.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.

Any number n=q1q2...q10 with qi a prime number
A prime number has exactly two factors.
Any composite number. Examples: 4 and 9 . . . (three factors) 6, 8, and 10 . . . (four factors) 12 . . . (six factors) 60 . . . (twelve factors)
no because every number is multiplied by 1 and it equals the same as the number...yay:D
