To determine if 2124 is a prime number or a composite number, we simply look at the factors for 2124.
If the factors of 2124 are only 2124 and 1, then we know that 2124 is a prime number. Otherwise, 2124 is a composite number.
To explain better, if 2124 is only divisible by 1 and 2124, then it is a prime number, and if 2124 is divisible by more than 2124 and 1, then it is a composite number.
The factors of 2124 are as follows:
1, 2, 3, 4, 6, 9, 12, 18, 36, 59, 118, 177, 236, 354, 531, 708, 1062, 2124
Therefore, since 2124 is divisible by more than one and itself, the answer to the
question "Is 2124 prime or composite?" is highlighted in blue below.
composite
Is 2125 prime or composite?
