To determine if 7715 is a prime number or a composite number, we simply look at the factors for 7715.
If the factors of 7715 are only 7715 and 1, then we know that 7715 is a prime number. Otherwise, 7715 is a composite number.
To explain better, if 7715 is only divisible by 1 and 7715, then it is a prime number, and if 7715 is divisible by more than 7715 and 1, then it is a composite number.
The factors of 7715 are as follows:
