To determine if 7771 is a prime number or a composite number, we simply look at the factors for 7771.
If the factors of 7771 are only 7771 and 1, then we know that 7771 is a prime number. Otherwise, 7771 is a composite number.
To explain better, if 7771 is only divisible by 1 and 7771, then it is a prime number, and if 7771 is divisible by more than 7771 and 1, then it is a composite number.
The factors of 7771 are as follows:
