To determine if 26 is a prime number or a composite number, we simply look at the factors for 26.
If the factors of 26 are only 26 and 1, then we know that 26 is a prime number. Otherwise, 26 is a composite number.
To explain better, if 26 is only divisible by 1 and 26, then it is a prime number, and if 26 is divisible by more than 26 and 1, then it is a composite number.
The factors of 26 are as follows:
1, 2, 13, 26
Therefore, since 26 is divisible by more than one and itself, the answer to the
question "Is 26 prime or composite?" is highlighted in blue below.
composite
Is 27 prime or composite?
OK. Now you know that 26 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.
