To determine if 5 is a prime number or a composite number, we simply look at the factors for 5.
If the factors of 5 are only 5 and 1, then we know that 5 is a prime number. Otherwise, 5 is a composite number.
To explain better, if 5 is only divisible by 1 and 5, then it is a prime number, and if 5 is divisible by more than 5 and 1, then it is a composite number.
The factors of 5 are as follows:
1, 5
Therefore, since 5 is divisible by only one and itself, the answer to the
question "Is 5 prime or composite?" is highlighted in blue below.
prime
Is 6 prime or composite?
OK. Now you know that 5 is a prime 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.
