To determine if 722 is a prime number or a composite number, we simply look at the factors for 722.
If the factors of 722 are only 722 and 1, then we know that 722 is a prime number. Otherwise, 722 is a composite number.
To explain better, if 722 is only divisible by 1 and 722, then it is a prime number, and if 722 is divisible by more than 722 and 1, then it is a composite number.
The factors of 722 are as follows:
1, 2, 19, 38, 361, 722
Therefore, since 722 is divisible by more than one and itself, the answer to the
question "Is 722 prime or composite?" is highlighted in blue below.
composite
Is 723 prime or composite?
OK. Now you know that 722 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.
