To determine if 2559 is a prime number or a composite number, we simply look at the factors for 2559.
If the factors of 2559 are only 2559 and 1, then we know that 2559 is a prime number. Otherwise, 2559 is a composite number.
To explain better, if 2559 is only divisible by 1 and 2559, then it is a prime number, and if 2559 is divisible by more than 2559 and 1, then it is a composite number.
The factors of 2559 are as follows:
