To determine if 459 is a prime number or a composite number, we simply look at the factors for 459.
If the factors of 459 are only 459 and 1, then we know that 459 is a prime number. Otherwise, 459 is a composite number.
To explain better, if 459 is only divisible by 1 and 459, then it is a prime number, and if 459 is divisible by more than 459 and 1, then it is a composite number.
The factors of 459 are as follows:
1, 3, 9, 17, 27, 51, 153, 459
Therefore, since 459 is divisible by more than one and itself, the answer to the
question "Is 459 prime or composite?" is highlighted in blue below.
composite
Is 460 prime or composite?
