To determine if 8555 is a prime number or a composite number, we simply look at the factors for 8555.
If the factors of 8555 are only 8555 and 1, then we know that 8555 is a prime number. Otherwise, 8555 is a composite number.
To explain better, if 8555 is only divisible by 1 and 8555, then it is a prime number, and if 8555 is divisible by more than 8555 and 1, then it is a composite number.
The factors of 8555 are as follows:
1, 5, 29, 59, 145, 295, 1711, 8555
