To determine if 238 is a prime number or a composite number, we simply look at the factors for 238.
If the factors of 238 are only 238 and 1, then we know that 238 is a prime number. Otherwise, 238 is a composite number.
To explain better, if 238 is only divisible by 1 and 238, then it is a prime number, and if 238 is divisible by more than 238 and 1, then it is a composite number.
The factors of 238 are as follows:
1, 2, 7, 14, 17, 34, 119, 238
Therefore, since 238 is divisible by more than one and itself, the answer to the
question "Is 238 prime or composite?" is highlighted in blue below.
composite
Is 239 prime or composite?
OK. Now you know that 238 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.
