To determine if 679 is a prime number or a composite number, we simply look at the factors for 679.
If the factors of 679 are only 679 and 1, then we know that 679 is a prime number. Otherwise, 679 is a composite number.
To explain better, if 679 is only divisible by 1 and 679, then it is a prime number, and if 679 is divisible by more than 679 and 1, then it is a composite number.
The factors of 679 are as follows:
1, 7, 97, 679
Therefore, since 679 is divisible by more than one and itself, the answer to the
question "Is 679 prime or composite?" is highlighted in blue below.
composite
Is 680 prime or composite?
