To determine if 2521 is a prime number or a composite number, we simply look at the factors for 2521.
If the factors of 2521 are only 2521 and 1, then we know that 2521 is a prime number. Otherwise, 2521 is a composite number.
To explain better, if 2521 is only divisible by 1 and 2521, then it is a prime number, and if 2521 is divisible by more than 2521 and 1, then it is a composite number.
The factors of 2521 are as follows:
