To determine if 3321 is a prime number or a composite number, we simply look at the factors for 3321.
If the factors of 3321 are only 3321 and 1, then we know that 3321 is a prime number. Otherwise, 3321 is a composite number.
To explain better, if 3321 is only divisible by 1 and 3321, then it is a prime number, and if 3321 is divisible by more than 3321 and 1, then it is a composite number.
The factors of 3321 are as follows:
1, 3, 9, 27, 41, 81, 123, 369, 1107, 3321
Therefore, since 3321 is divisible by more than one and itself, the answer to the
question "Is 3321 prime or composite?" is highlighted in blue below.
