To determine if 5151 is a prime number or a composite number, we simply look at the factors for 5151.
If the factors of 5151 are only 5151 and 1, then we know that 5151 is a prime number. Otherwise, 5151 is a composite number.
To explain better, if 5151 is only divisible by 1 and 5151, then it is a prime number, and if 5151 is divisible by more than 5151 and 1, then it is a composite number.
The factors of 5151 are as follows:
1, 3, 17, 51, 101, 303, 1717, 5151
Therefore, since 5151 is divisible by more than one and itself, the answer to the
question "Is 5151 prime or composite?" is highlighted in blue below.
