To determine if 497 is a prime number or a composite number, we simply look at the factors for 497.
If the factors of 497 are only 497 and 1, then we know that 497 is a prime number. Otherwise, 497 is a composite number.
To explain better, if 497 is only divisible by 1 and 497, then it is a prime number, and if 497 is divisible by more than 497 and 1, then it is a composite number.
The factors of 497 are as follows:
1, 7, 71, 497
Therefore, since 497 is divisible by more than one and itself, the answer to the
question "Is 497 prime or composite?" is highlighted in blue below.
composite
Is 498 prime or composite?
