To determine if 6515 is a prime number or a composite number, we simply look at the factors for 6515.
If the factors of 6515 are only 6515 and 1, then we know that 6515 is a prime number. Otherwise, 6515 is a composite number.
To explain better, if 6515 is only divisible by 1 and 6515, then it is a prime number, and if 6515 is divisible by more than 6515 and 1, then it is a composite number.
The factors of 6515 are as follows:
