To determine if 2851 is a prime number or a composite number, we simply look at the factors for 2851.
If the factors of 2851 are only 2851 and 1, then we know that 2851 is a prime number. Otherwise, 2851 is a composite number.
To explain better, if 2851 is only divisible by 1 and 2851, then it is a prime number, and if 2851 is divisible by more than 2851 and 1, then it is a composite number.
The factors of 2851 are as follows:
