To determine if 7876 is a prime number or a composite number, we simply look at the factors for 7876.
If the factors of 7876 are only 7876 and 1, then we know that 7876 is a prime number. Otherwise, 7876 is a composite number.
To explain better, if 7876 is only divisible by 1 and 7876, then it is a prime number, and if 7876 is divisible by more than 7876 and 1, then it is a composite number.
The factors of 7876 are as follows:
