To determine if 8135 is a prime number or a composite number, we simply look at the factors for 8135.
If the factors of 8135 are only 8135 and 1, then we know that 8135 is a prime number. Otherwise, 8135 is a composite number.
To explain better, if 8135 is only divisible by 1 and 8135, then it is a prime number, and if 8135 is divisible by more than 8135 and 1, then it is a composite number.
The factors of 8135 are as follows:
