To determine if 338 is a prime number or a composite number, we simply look at the factors for 338.
If the factors of 338 are only 338 and 1, then we know that 338 is a prime number. Otherwise, 338 is a composite number.
To explain better, if 338 is only divisible by 1 and 338, then it is a prime number, and if 338 is divisible by more than 338 and 1, then it is a composite number.
The factors of 338 are as follows:
1, 2, 13, 26, 169, 338
Therefore, since 338 is divisible by more than one and itself, the answer to the
question "Is 338 prime or composite?" is highlighted in blue below.
composite
Is 339 prime or composite?
OK. Now you know that 338 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.
