To determine if 117 is a prime number or a composite number, we simply look at the factors for 117.
If the factors of 117 are only 117 and 1, then we know that 117 is a prime number. Otherwise, 117 is a composite number.
To explain better, if 117 is only divisible by 1 and 117, then it is a prime number, and if 117 is divisible by more than 117 and 1, then it is a composite number.
The factors of 117 are as follows:
1, 3, 9, 13, 39, 117
Therefore, since 117 is divisible by more than one and itself, the answer to the
question "Is 117 prime or composite?" is highlighted in blue below.
composite
Is 118 prime or composite?
OK. Now you know that 117 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.
