To determine if 111 is a prime number or a composite number, we simply look at the factors for 111.
If the factors of 111 are only 111 and 1, then we know that 111 is a prime number. Otherwise, 111 is a composite number.
To explain better, if 111 is only divisible by 1 and 111, then it is a prime number, and if 111 is divisible by more than 111 and 1, then it is a composite number.
The factors of 111 are as follows:
1, 3, 37, 111
Therefore, since 111 is divisible by more than one and itself, the answer to the
question "Is 111 prime or composite?" is highlighted in blue below.
composite
Is 112 prime or composite?
OK. Now you know that 111 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.
