To determine if 270 is a prime number or a composite number, we simply look at the factors for 270.
If the factors of 270 are only 270 and 1, then we know that 270 is a prime number. Otherwise, 270 is a composite number.
To explain better, if 270 is only divisible by 1 and 270, then it is a prime number, and if 270 is divisible by more than 270 and 1, then it is a composite number.
The factors of 270 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
Therefore, since 270 is divisible by more than one and itself, the answer to the
question "Is 270 prime or composite?" is highlighted in blue below.
composite
Is 271 prime or composite?
OK. Now you know that 270 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.
