To determine if 8321 is a prime number or a composite number, we simply look at the factors for 8321.
If the factors of 8321 are only 8321 and 1, then we know that 8321 is a prime number. Otherwise, 8321 is a composite number.
To explain better, if 8321 is only divisible by 1 and 8321, then it is a prime number, and if 8321 is divisible by more than 8321 and 1, then it is a composite number.
The factors of 8321 are as follows:
1, 53, 157, 8321
Therefore, since 8321 is divisible by more than one and itself, the answer to the
question "Is 8321 prime or composite?" is highlighted in blue below.
composite
