To determine if 5128 is a prime number or a composite number, we simply look at the factors for 5128.
If the factors of 5128 are only 5128 and 1, then we know that 5128 is a prime number. Otherwise, 5128 is a composite number.
To explain better, if 5128 is only divisible by 1 and 5128, then it is a prime number, and if 5128 is divisible by more than 5128 and 1, then it is a composite number.
The factors of 5128 are as follows:
1, 2, 4, 8, 641, 1282, 2564, 5128
Therefore, since 5128 is divisible by more than one and itself, the answer to the
question "Is 5128 prime or composite?" is highlighted in blue below.
