To determine if 3111 is a prime number or a composite number, we simply look at the factors for 3111.
If the factors of 3111 are only 3111 and 1, then we know that 3111 is a prime number. Otherwise, 3111 is a composite number.
To explain better, if 3111 is only divisible by 1 and 3111, then it is a prime number, and if 3111 is divisible by more than 3111 and 1, then it is a composite number.
The factors of 3111 are as follows:
1, 3, 17, 51, 61, 183, 1037, 3111
Therefore, since 3111 is divisible by more than one and itself, the answer to the
question "Is 3111 prime or composite?" is highlighted in blue below.
composite
