To determine if 6 is a prime number or a composite number, we simply look at the factors for 6.
If the factors of 6 are only 6 and 1, then we know that 6 is a prime number. Otherwise, 6 is a composite number.
To explain better, if 6 is only divisible by 1 and 6, then it is a prime number, and if 6 is divisible by more than 6 and 1, then it is a composite number.
The factors of 6 are as follows:
1, 2, 3, 6
Therefore, since 6 is divisible by more than one and itself, the answer to the
question "Is 6 prime or composite?" is highlighted in blue below.
composite
Is 7 prime or composite?
OK. Now you know that 6 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.
