To determine if 3218 is a prime number or a composite number, we simply look at the factors for 3218.
If the factors of 3218 are only 3218 and 1, then we know that 3218 is a prime number. Otherwise, 3218 is a composite number.
To explain better, if 3218 is only divisible by 1 and 3218, then it is a prime number, and if 3218 is divisible by more than 3218 and 1, then it is a composite number.
The factors of 3218 are as follows:
1, 2, 1609, 3218
Therefore, since 3218 is divisible by more than one and itself, the answer to the
question "Is 3218 prime or composite?" is highlighted in blue below.
