To determine if 422 is a prime number or a composite number, we simply look at the factors for 422.
If the factors of 422 are only 422 and 1, then we know that 422 is a prime number. Otherwise, 422 is a composite number.
To explain better, if 422 is only divisible by 1 and 422, then it is a prime number, and if 422 is divisible by more than 422 and 1, then it is a composite number.
The factors of 422 are as follows:
1, 2, 211, 422
Therefore, since 422 is divisible by more than one and itself, the answer to the
question "Is 422 prime or composite?" is highlighted in blue below.
composite
Is 423 prime or composite?
OK. Now you know that 422 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.
