To determine if 6321 is a prime number or a composite number, we simply look at the factors for 6321.
If the factors of 6321 are only 6321 and 1, then we know that 6321 is a prime number. Otherwise, 6321 is a composite number.
To explain better, if 6321 is only divisible by 1 and 6321, then it is a prime number, and if 6321 is divisible by more than 6321 and 1, then it is a composite number.
The factors of 6321 are as follows:
1, 3, 7, 21, 43, 49, 129, 147, 301, 903, 2107, 6321
Therefore, since 6321 is divisible by more than one and itself, the answer to the
question "Is 6321 prime or composite?" is highlighted in blue below.
