To determine if 3138 is a prime number or a composite number, we simply look at the factors for 3138.
If the factors of 3138 are only 3138 and 1, then we know that 3138 is a prime number. Otherwise, 3138 is a composite number.
To explain better, if 3138 is only divisible by 1 and 3138, then it is a prime number, and if 3138 is divisible by more than 3138 and 1, then it is a composite number.
The factors of 3138 are as follows:
1, 2, 3, 6, 523, 1046, 1569, 3138
Therefore, since 3138 is divisible by more than one and itself, the answer to the
