To determine if 2845 is a prime number or a composite number, we simply look at the factors for 2845.
If the factors of 2845 are only 2845 and 1, then we know that 2845 is a prime number. Otherwise, 2845 is a composite number.
To explain better, if 2845 is only divisible by 1 and 2845, then it is a prime number, and if 2845 is divisible by more than 2845 and 1, then it is a composite number.
The factors of 2845 are as follows:
