To determine if 2223 is a prime number or a composite number, we simply look at the factors for 2223.
If the factors of 2223 are only 2223 and 1, then we know that 2223 is a prime number. Otherwise, 2223 is a composite number.
To explain better, if 2223 is only divisible by 1 and 2223, then it is a prime number, and if 2223 is divisible by more than 2223 and 1, then it is a composite number.
The factors of 2223 are as follows:
1, 3, 9, 13, 19, 39, 57, 117, 171, 247, 741, 2223
Therefore, since 2223 is divisible by more than one and itself, the answer to the
question "Is 2223 prime or composite?" is highlighted in blue below.
composite
Is 2224 prime or composite?
