To determine if 9821 is a prime number or a composite number, we simply look at the factors for 9821.
If the factors of 9821 are only 9821 and 1, then we know that 9821 is a prime number. Otherwise, 9821 is a composite number.
To explain better, if 9821 is only divisible by 1 and 9821, then it is a prime number, and if 9821 is divisible by more than 9821 and 1, then it is a composite number.
The factors of 9821 are as follows:
1, 7, 23, 61, 161, 427, 1403, 9821
