To determine if 275 is a prime number or a composite number, we simply look at the factors for 275.
If the factors of 275 are only 275 and 1, then we know that 275 is a prime number. Otherwise, 275 is a composite number.
To explain better, if 275 is only divisible by 1 and 275, then it is a prime number, and if 275 is divisible by more than 275 and 1, then it is a composite number.
The factors of 275 are as follows:
1, 5, 11, 25, 55, 275
Therefore, since 275 is divisible by more than one and itself, the answer to the
question "Is 275 prime or composite?" is highlighted in blue below.
composite
Is 276 prime or composite?
OK. Now you know that 275 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.
