To determine if 7124 is a prime number or a composite number, we simply look at the factors for 7124.
If the factors of 7124 are only 7124 and 1, then we know that 7124 is a prime number. Otherwise, 7124 is a composite number.
To explain better, if 7124 is only divisible by 1 and 7124, then it is a prime number, and if 7124 is divisible by more than 7124 and 1, then it is a composite number.
The factors of 7124 are as follows:
1, 2, 4, 13, 26, 52, 137, 274, 548, 1781, 3562, 7124
Therefore, since 7124 is divisible by more than one and itself, the answer to the
question "Is 7124 prime or composite?" is highlighted in blue below.
