To determine if 108 is a prime number or a composite number, we simply look at the factors for 108.
If the factors of 108 are only 108 and 1, then we know that 108 is a prime number. Otherwise, 108 is a composite number.
To explain better, if 108 is only divisible by 1 and 108, then it is a prime number, and if 108 is divisible by more than 108 and 1, then it is a composite number.
The factors of 108 are as follows:
1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
Therefore, since 108 is divisible by more than one and itself, the answer to the
question "Is 108 prime or composite?" is highlighted in blue below.
composite
Is 109 prime or composite?
OK. Now you know that 108 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
