To determine if 458 is a prime number or a composite number, we simply look at the factors for 458.
If the factors of 458 are only 458 and 1, then we know that 458 is a prime number. Otherwise, 458 is a composite number.
To explain better, if 458 is only divisible by 1 and 458, then it is a prime number, and if 458 is divisible by more than 458 and 1, then it is a composite number.
The factors of 458 are as follows:
1, 2, 229, 458
Therefore, since 458 is divisible by more than one and itself, the answer to the
question "Is 458 prime or composite?" is highlighted in blue below.
composite
Is 459 prime or composite?
OK. Now you know that 458 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.
