To determine if 724 is a prime number or a composite number, we simply look at the factors for 724.
If the factors of 724 are only 724 and 1, then we know that 724 is a prime number. Otherwise, 724 is a composite number.
To explain better, if 724 is only divisible by 1 and 724, then it is a prime number, and if 724 is divisible by more than 724 and 1, then it is a composite number.
The factors of 724 are as follows:
1, 2, 4, 181, 362, 724
Therefore, since 724 is divisible by more than one and itself, the answer to the
question "Is 724 prime or composite?" is highlighted in blue below.
composite
Is 725 prime or composite?
OK. Now you know that 724 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.
