To determine if 3127 is a prime number or a composite number, we simply look at the factors for 3127.
If the factors of 3127 are only 3127 and 1, then we know that 3127 is a prime number. Otherwise, 3127 is a composite number.
To explain better, if 3127 is only divisible by 1 and 3127, then it is a prime number, and if 3127 is divisible by more than 3127 and 1, then it is a composite number.
The factors of 3127 are as follows:
