To determine if 223 is a prime number or a composite number, we simply look at the factors for 223.
If the factors of 223 are only 223 and 1, then we know that 223 is a prime number. Otherwise, 223 is a composite number.
To explain better, if 223 is only divisible by 1 and 223, then it is a prime number, and if 223 is divisible by more than 223 and 1, then it is a composite number.
The factors of 223 are as follows:
1, 223
Therefore, since 223 is divisible by only one and itself, the answer to the
question "Is 223 prime or composite?" is highlighted in blue below.
prime
Is 224 prime or composite?
