To determine if 122 is a prime number or a composite number, we simply look at the factors for 122.
If the factors of 122 are only 122 and 1, then we know that 122 is a prime number. Otherwise, 122 is a composite number.
To explain better, if 122 is only divisible by 1 and 122, then it is a prime number, and if 122 is divisible by more than 122 and 1, then it is a composite number.
The factors of 122 are as follows:
1, 2, 61, 122
Therefore, since 122 is divisible by more than one and itself, the answer to the
question "Is 122 prime or composite?" is highlighted in blue below.
composite
Is 123 prime or composite?
OK. Now you know that 122 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.
