To determine if 7911 is a prime number or a composite number, we simply look at the factors for 7911.
If the factors of 7911 are only 7911 and 1, then we know that 7911 is a prime number. Otherwise, 7911 is a composite number.
To explain better, if 7911 is only divisible by 1 and 7911, then it is a prime number, and if 7911 is divisible by more than 7911 and 1, then it is a composite number.
The factors of 7911 are as follows:
1, 3, 9, 27, 293, 879, 2637, 7911
