To determine if 109 is a prime number or a composite number, we simply look at the factors for 109.
If the factors of 109 are only 109 and 1, then we know that 109 is a prime number. Otherwise, 109 is a composite number.
To explain better, if 109 is only divisible by 1 and 109, then it is a prime number, and if 109 is divisible by more than 109 and 1, then it is a composite number.
The factors of 109 are as follows:
1, 109
Therefore, since 109 is divisible by only one and itself, the answer to the
question "Is 109 prime or composite?" is highlighted in blue below.
prime
Is 110 prime or composite?
