To determine if 5138 is a prime number or a composite number, we simply look at the factors for 5138.
If the factors of 5138 are only 5138 and 1, then we know that 5138 is a prime number. Otherwise, 5138 is a composite number.
To explain better, if 5138 is only divisible by 1 and 5138, then it is a prime number, and if 5138 is divisible by more than 5138 and 1, then it is a composite number.
The factors of 5138 are as follows:
1, 2, 7, 14, 367, 734, 2569, 5138
Therefore, since 5138 is divisible by more than one and itself, the answer to the
