To determine if 2809 is a prime number or a composite number, we simply look at the factors for 2809.
If the factors of 2809 are only 2809 and 1, then we know that 2809 is a prime number. Otherwise, 2809 is a composite number.
To explain better, if 2809 is only divisible by 1 and 2809, then it is a prime number, and if 2809 is divisible by more than 2809 and 1, then it is a composite number.
The factors of 2809 are as follows:
