To determine if 9805 is a prime number or a composite number, we simply look at the factors for 9805.
If the factors of 9805 are only 9805 and 1, then we know that 9805 is a prime number. Otherwise, 9805 is a composite number.
To explain better, if 9805 is only divisible by 1 and 9805, then it is a prime number, and if 9805 is divisible by more than 9805 and 1, then it is a composite number.
The factors of 9805 are as follows:
