To determine if 8155 is a prime number or a composite number, we simply look at the factors for 8155.
If the factors of 8155 are only 8155 and 1, then we know that 8155 is a prime number. Otherwise, 8155 is a composite number.
To explain better, if 8155 is only divisible by 1 and 8155, then it is a prime number, and if 8155 is divisible by more than 8155 and 1, then it is a composite number.
The factors of 8155 are as follows:
