To determine if 5390 is a prime number or a composite number, we simply look at the factors for 5390.
If the factors of 5390 are only 5390 and 1, then we know that 5390 is a prime number. Otherwise, 5390 is a composite number.
To explain better, if 5390 is only divisible by 1 and 5390, then it is a prime number, and if 5390 is divisible by more than 5390 and 1, then it is a composite number.
The factors of 5390 are as follows:
1, 2, 5, 7, 10, 11, 14, 22, 35, 49, 55, 70, 77, 98, 110, 154, 245, 385, 490, 539, 770, 1078, 2695, 5390
Therefore, since 5390 is divisible by more than one and itself, the answer to the
question "Is 5390 prime or composite?" is highlighted in blue below.
