To determine if 626 is a prime number or a composite number, we simply look at the factors for 626.
If the factors of 626 are only 626 and 1, then we know that 626 is a prime number. Otherwise, 626 is a composite number.
To explain better, if 626 is only divisible by 1 and 626, then it is a prime number, and if 626 is divisible by more than 626 and 1, then it is a composite number.
The factors of 626 are as follows:
1, 2, 313, 626
Therefore, since 626 is divisible by more than one and itself, the answer to the
question "Is 626 prime or composite?" is highlighted in blue below.
composite
Is 627 prime or composite?
