To determine if 37 is a prime number or a composite number, we simply look at the factors for 37.
If the factors of 37 are only 37 and 1, then we know that 37 is a prime number. Otherwise, 37 is a composite number.
To explain better, if 37 is only divisible by 1 and 37, then it is a prime number, and if 37 is divisible by more than 37 and 1, then it is a composite number.
The factors of 37 are as follows:
1, 37
Therefore, since 37 is divisible by only one and itself, the answer to the
question "Is 37 prime or composite?" is highlighted in blue below.
prime
Is 38 prime or composite?
