To determine if 5140 is a prime number or a composite number, we simply look at the factors for 5140.
If the factors of 5140 are only 5140 and 1, then we know that 5140 is a prime number. Otherwise, 5140 is a composite number.
To explain better, if 5140 is only divisible by 1 and 5140, then it is a prime number, and if 5140 is divisible by more than 5140 and 1, then it is a composite number.
The factors of 5140 are as follows:
1, 2, 4, 5, 10, 20, 257, 514, 1028, 1285, 2570, 5140
Therefore, since 5140 is divisible by more than one and itself, the answer to the
question "Is 5140 prime or composite?" is highlighted in blue below.
composite
Is 5141 prime or composite?
