To determine if 14 is a prime number or a composite number, we simply look at the factors for 14.
If the factors of 14 are only 14 and 1, then we know that 14 is a prime number. Otherwise, 14 is a composite number.
To explain better, if 14 is only divisible by 1 and 14, then it is a prime number, and if 14 is divisible by more than 14 and 1, then it is a composite number.
The factors of 14 are as follows:
1, 2, 7, 14
Therefore, since 14 is divisible by more than one and itself, the answer to the
question "Is 14 prime or composite?" is highlighted in blue below.
composite
Is 15 prime or composite?
OK. Now you know that 14 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.
