To determine if 731 is a prime number or a composite number, we simply look at the factors for 731.
If the factors of 731 are only 731 and 1, then we know that 731 is a prime number. Otherwise, 731 is a composite number.
To explain better, if 731 is only divisible by 1 and 731, then it is a prime number, and if 731 is divisible by more than 731 and 1, then it is a composite number.
The factors of 731 are as follows:
1, 17, 43, 731
Therefore, since 731 is divisible by more than one and itself, the answer to the
question "Is 731 prime or composite?" is highlighted in blue below.
composite
Is 732 prime or composite?
OK. Now you know that 731 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.
