To determine if 5187 is a prime number or a composite number, we simply look at the factors for 5187.
If the factors of 5187 are only 5187 and 1, then we know that 5187 is a prime number. Otherwise, 5187 is a composite number.
To explain better, if 5187 is only divisible by 1 and 5187, then it is a prime number, and if 5187 is divisible by more than 5187 and 1, then it is a composite number.
The factors of 5187 are as follows:
1, 3, 7, 13, 19, 21, 39, 57, 91, 133, 247, 273, 399, 741, 1729, 5187
Therefore, since 5187 is divisible by more than one and itself, the answer to the
question "Is 5187 prime or composite?" is highlighted in blue below.
