To determine if 224 is a prime number or a composite number, we simply look at the factors for 224.
If the factors of 224 are only 224 and 1, then we know that 224 is a prime number. Otherwise, 224 is a composite number.
To explain better, if 224 is only divisible by 1 and 224, then it is a prime number, and if 224 is divisible by more than 224 and 1, then it is a composite number.
The factors of 224 are as follows:
1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
Therefore, since 224 is divisible by more than one and itself, the answer to the
question "Is 224 prime or composite?" is highlighted in blue below.
composite
Is 225 prime or composite?
OK. Now you know that 224 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
