To determine if 8603 is a prime number or a composite number, we simply look at the factors for 8603.
If the factors of 8603 are only 8603 and 1, then we know that 8603 is a prime number. Otherwise, 8603 is a composite number.
To explain better, if 8603 is only divisible by 1 and 8603, then it is a prime number, and if 8603 is divisible by more than 8603 and 1, then it is a composite number.
The factors of 8603 are as follows:
