To determine if 2218 is a prime number or a composite number, we simply look at the factors for 2218.
If the factors of 2218 are only 2218 and 1, then we know that 2218 is a prime number. Otherwise, 2218 is a composite number.
To explain better, if 2218 is only divisible by 1 and 2218, then it is a prime number, and if 2218 is divisible by more than 2218 and 1, then it is a composite number.
The factors of 2218 are as follows:
1, 2, 1109, 2218
Therefore, since 2218 is divisible by more than one and itself, the answer to the
question "Is 2218 prime or composite?" is highlighted in blue below.
composite
Is 2219 prime or composite?
