To determine if 2379 is a prime number or a composite number, we simply look at the factors for 2379.
If the factors of 2379 are only 2379 and 1, then we know that 2379 is a prime number. Otherwise, 2379 is a composite number.
To explain better, if 2379 is only divisible by 1 and 2379, then it is a prime number, and if 2379 is divisible by more than 2379 and 1, then it is a composite number.
The factors of 2379 are as follows:
1, 3, 13, 39, 61, 183, 793, 2379
Therefore, since 2379 is divisible by more than one and itself, the answer to the
