To determine if 9775 is a prime number or a composite number, we simply look at the factors for 9775.
If the factors of 9775 are only 9775 and 1, then we know that 9775 is a prime number. Otherwise, 9775 is a composite number.
To explain better, if 9775 is only divisible by 1 and 9775, then it is a prime number, and if 9775 is divisible by more than 9775 and 1, then it is a composite number.
The factors of 9775 are as follows:
