To determine if 8585 is a prime number or a composite number, we simply look at the factors for 8585.
If the factors of 8585 are only 8585 and 1, then we know that 8585 is a prime number. Otherwise, 8585 is a composite number.
To explain better, if 8585 is only divisible by 1 and 8585, then it is a prime number, and if 8585 is divisible by more than 8585 and 1, then it is a composite number.
The factors of 8585 are as follows:
