To determine if 634 is a prime number or a composite number, we simply look at the factors for 634.
If the factors of 634 are only 634 and 1, then we know that 634 is a prime number. Otherwise, 634 is a composite number.
To explain better, if 634 is only divisible by 1 and 634, then it is a prime number, and if 634 is divisible by more than 634 and 1, then it is a composite number.
The factors of 634 are as follows:
1, 2, 317, 634
Therefore, since 634 is divisible by more than one and itself, the answer to the
question "Is 634 prime or composite?" is highlighted in blue below.
composite
Is 635 prime or composite?
