To determine if 7224 is a prime number or a composite number, we simply look at the factors for 7224.
If the factors of 7224 are only 7224 and 1, then we know that 7224 is a prime number. Otherwise, 7224 is a composite number.
To explain better, if 7224 is only divisible by 1 and 7224, then it is a prime number, and if 7224 is divisible by more than 7224 and 1, then it is a composite number.
The factors of 7224 are as follows:
1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 43, 56, 84, 86, 129, 168, 172, 258, 301, 344, 516, 602, 903, 1032, 1204, 1806, 2408, 3612, 7224
Therefore, since 7224 is divisible by more than one and itself, the answer to the
question "Is 7224 prime or composite?" is highlighted in blue below.
