To determine if 6441 is a prime number or a composite number, we simply look at the factors for 6441.
If the factors of 6441 are only 6441 and 1, then we know that 6441 is a prime number. Otherwise, 6441 is a composite number.
To explain better, if 6441 is only divisible by 1 and 6441, then it is a prime number, and if 6441 is divisible by more than 6441 and 1, then it is a composite number.
The factors of 6441 are as follows:
1, 3, 19, 57, 113, 339, 2147, 6441
