To determine if 5105 is a prime number or a composite number, we simply look at the factors for 5105.
If the factors of 5105 are only 5105 and 1, then we know that 5105 is a prime number. Otherwise, 5105 is a composite number.
To explain better, if 5105 is only divisible by 1 and 5105, then it is a prime number, and if 5105 is divisible by more than 5105 and 1, then it is a composite number.
The factors of 5105 are as follows:
1, 5, 1021, 5105
Therefore, since 5105 is divisible by more than one and itself, the answer to the
question "Is 5105 prime or composite?" is highlighted in blue below.
composite
Is 5106 prime or composite?
