To determine if 676 is a prime number or a composite number, we simply look at the factors for 676.
If the factors of 676 are only 676 and 1, then we know that 676 is a prime number. Otherwise, 676 is a composite number.
To explain better, if 676 is only divisible by 1 and 676, then it is a prime number, and if 676 is divisible by more than 676 and 1, then it is a composite number.
The factors of 676 are as follows:
1, 2, 4, 13, 26, 52, 169, 338, 676
Therefore, since 676 is divisible by more than one and itself, the answer to the
question "Is 676 prime or composite?" is highlighted in blue below.
composite
Is 677 prime or composite?
