To determine if 5123 is a prime number or a composite number, we simply look at the factors for 5123.
If the factors of 5123 are only 5123 and 1, then we know that 5123 is a prime number. Otherwise, 5123 is a composite number.
To explain better, if 5123 is only divisible by 1 and 5123, then it is a prime number, and if 5123 is divisible by more than 5123 and 1, then it is a composite number.
The factors of 5123 are as follows:
1, 47, 109, 5123
Therefore, since 5123 is divisible by more than one and itself, the answer to the
question "Is 5123 prime or composite?" is highlighted in blue below.
composite
