To determine if 454 is a prime number or a composite number, we simply look at the factors for 454.
If the factors of 454 are only 454 and 1, then we know that 454 is a prime number. Otherwise, 454 is a composite number.
To explain better, if 454 is only divisible by 1 and 454, then it is a prime number, and if 454 is divisible by more than 454 and 1, then it is a composite number.
The factors of 454 are as follows:
1, 2, 227, 454
Therefore, since 454 is divisible by more than one and itself, the answer to the
question "Is 454 prime or composite?" is highlighted in blue below.
composite
Is 455 prime or composite?
