To determine if 3124 is a prime number or a composite number, we simply look at the factors for 3124.
If the factors of 3124 are only 3124 and 1, then we know that 3124 is a prime number. Otherwise, 3124 is a composite number.
To explain better, if 3124 is only divisible by 1 and 3124, then it is a prime number, and if 3124 is divisible by more than 3124 and 1, then it is a composite number.
The factors of 3124 are as follows:
1, 2, 4, 11, 22, 44, 71, 142, 284, 781, 1562, 3124
Therefore, since 3124 is divisible by more than one and itself, the answer to the
question "Is 3124 prime or composite?" is highlighted in blue below.
composite
