To determine if 726 is a prime number or a composite number, we simply look at the factors for 726.
If the factors of 726 are only 726 and 1, then we know that 726 is a prime number. Otherwise, 726 is a composite number.
To explain better, if 726 is only divisible by 1 and 726, then it is a prime number, and if 726 is divisible by more than 726 and 1, then it is a composite number.
The factors of 726 are as follows:
1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
Therefore, since 726 is divisible by more than one and itself, the answer to the
question "Is 726 prime or composite?" is highlighted in blue below.
composite
Is 727 prime or composite?
