To determine if 730 is a prime number or a composite number, we simply look at the factors for 730.
If the factors of 730 are only 730 and 1, then we know that 730 is a prime number. Otherwise, 730 is a composite number.
To explain better, if 730 is only divisible by 1 and 730, then it is a prime number, and if 730 is divisible by more than 730 and 1, then it is a composite number.
The factors of 730 are as follows:
1, 2, 5, 10, 73, 146, 365, 730
Therefore, since 730 is divisible by more than one and itself, the answer to the
question "Is 730 prime or composite?" is highlighted in blue below.
composite
Is 731 prime or composite?
OK. Now you know that 730 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.
