To determine if 563 is a prime number or a composite number, we simply look at the factors for 563.
If the factors of 563 are only 563 and 1, then we know that 563 is a prime number. Otherwise, 563 is a composite number.
To explain better, if 563 is only divisible by 1 and 563, then it is a prime number, and if 563 is divisible by more than 563 and 1, then it is a composite number.
The factors of 563 are as follows:
