To determine if 674 is a prime number or a composite number, we simply look at the factors for 674.
If the factors of 674 are only 674 and 1, then we know that 674 is a prime number. Otherwise, 674 is a composite number.
To explain better, if 674 is only divisible by 1 and 674, then it is a prime number, and if 674 is divisible by more than 674 and 1, then it is a composite number.
The factors of 674 are as follows:
1, 2, 337, 674
Therefore, since 674 is divisible by more than one and itself, the answer to the
question "Is 674 prime or composite?" is highlighted in blue below.
composite
Is 675 prime or composite?
