To determine if 7641 is a prime number or a composite number, we simply look at the factors for 7641.
If the factors of 7641 are only 7641 and 1, then we know that 7641 is a prime number. Otherwise, 7641 is a composite number.
To explain better, if 7641 is only divisible by 1 and 7641, then it is a prime number, and if 7641 is divisible by more than 7641 and 1, then it is a composite number.
The factors of 7641 are as follows:
1, 3, 9, 27, 283, 849, 2547, 7641
