To determine if 9825 is a prime number or a composite number, we simply look at the factors for 9825.
If the factors of 9825 are only 9825 and 1, then we know that 9825 is a prime number. Otherwise, 9825 is a composite number.
To explain better, if 9825 is only divisible by 1 and 9825, then it is a prime number, and if 9825 is divisible by more than 9825 and 1, then it is a composite number.
The factors of 9825 are as follows:
