To determine if 537 is a prime number or a composite number, we simply look at the factors for 537.
If the factors of 537 are only 537 and 1, then we know that 537 is a prime number. Otherwise, 537 is a composite number.
To explain better, if 537 is only divisible by 1 and 537, then it is a prime number, and if 537 is divisible by more than 537 and 1, then it is a composite number.
The factors of 537 are as follows:
1, 3, 179, 537
Therefore, since 537 is divisible by more than one and itself, the answer to the
question "Is 537 prime or composite?" is highlighted in blue below.
composite
Is 538 prime or composite?
