To determine if 2785 is a prime number or a composite number, we simply look at the factors for 2785.
If the factors of 2785 are only 2785 and 1, then we know that 2785 is a prime number. Otherwise, 2785 is a composite number.
To explain better, if 2785 is only divisible by 1 and 2785, then it is a prime number, and if 2785 is divisible by more than 2785 and 1, then it is a composite number.
The factors of 2785 are as follows:
