To determine if 5391 is a prime number or a composite number, we simply look at the factors for 5391.
If the factors of 5391 are only 5391 and 1, then we know that 5391 is a prime number. Otherwise, 5391 is a composite number.
To explain better, if 5391 is only divisible by 1 and 5391, then it is a prime number, and if 5391 is divisible by more than 5391 and 1, then it is a composite number.
The factors of 5391 are as follows:
1, 3, 9, 599, 1797, 5391
Therefore, since 5391 is divisible by more than one and itself, the answer to the
question "Is 5391 prime or composite?" is highlighted in blue below.
