To determine if 629 is a prime number or a composite number, we simply look at the factors for 629.
If the factors of 629 are only 629 and 1, then we know that 629 is a prime number. Otherwise, 629 is a composite number.
To explain better, if 629 is only divisible by 1 and 629, then it is a prime number, and if 629 is divisible by more than 629 and 1, then it is a composite number.
The factors of 629 are as follows:
1, 17, 37, 629
Therefore, since 629 is divisible by more than one and itself, the answer to the
question "Is 629 prime or composite?" is highlighted in blue below.
composite
Is 630 prime or composite?
