To determine if 879 is a prime number or a composite number, we simply look at the factors for 879.
If the factors of 879 are only 879 and 1, then we know that 879 is a prime number. Otherwise, 879 is a composite number.
To explain better, if 879 is only divisible by 1 and 879, then it is a prime number, and if 879 is divisible by more than 879 and 1, then it is a composite number.
The factors of 879 are as follows:
1, 3, 293, 879
Therefore, since 879 is divisible by more than one and itself, the answer to the
question "Is 879 prime or composite?" is highlighted in blue below.
composite
Is 880 prime or composite?
