To determine if 424 is a prime number or a composite number, we simply look at the factors for 424.
If the factors of 424 are only 424 and 1, then we know that 424 is a prime number. Otherwise, 424 is a composite number.
To explain better, if 424 is only divisible by 1 and 424, then it is a prime number, and if 424 is divisible by more than 424 and 1, then it is a composite number.
The factors of 424 are as follows:
1, 2, 4, 8, 53, 106, 212, 424
Therefore, since 424 is divisible by more than one and itself, the answer to the
question "Is 424 prime or composite?" is highlighted in blue below.
composite
Is 425 prime or composite?
