To determine if 9581 is a prime number or a composite number, we simply look at the factors for 9581.
If the factors of 9581 are only 9581 and 1, then we know that 9581 is a prime number. Otherwise, 9581 is a composite number.
To explain better, if 9581 is only divisible by 1 and 9581, then it is a prime number, and if 9581 is divisible by more than 9581 and 1, then it is a composite number.
The factors of 9581 are as follows:
1, 11, 13, 67, 143, 737, 871, 9581
