To determine if 426 is a prime number or a composite number, we simply look at the factors for 426.
If the factors of 426 are only 426 and 1, then we know that 426 is a prime number. Otherwise, 426 is a composite number.
To explain better, if 426 is only divisible by 1 and 426, then it is a prime number, and if 426 is divisible by more than 426 and 1, then it is a composite number.
The factors of 426 are as follows:
1, 2, 3, 6, 71, 142, 213, 426
Therefore, since 426 is divisible by more than one and itself, the answer to the
question "Is 426 prime or composite?" is highlighted in blue below.
composite
Is 427 prime or composite?
OK. Now you know that 426 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.
