To determine if 242 is a prime number or a composite number, we simply look at the factors for 242.
If the factors of 242 are only 242 and 1, then we know that 242 is a prime number. Otherwise, 242 is a composite number.
To explain better, if 242 is only divisible by 1 and 242, then it is a prime number, and if 242 is divisible by more than 242 and 1, then it is a composite number.
The factors of 242 are as follows:
1, 2, 11, 22, 121, 242
Therefore, since 242 is divisible by more than one and itself, the answer to the
question "Is 242 prime or composite?" is highlighted in blue below.
composite
Is 243 prime or composite?
OK. Now you know that 242 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.
