To determine if 276 is a prime number or a composite number, we simply look at the factors for 276.
If the factors of 276 are only 276 and 1, then we know that 276 is a prime number. Otherwise, 276 is a composite number.
To explain better, if 276 is only divisible by 1 and 276, then it is a prime number, and if 276 is divisible by more than 276 and 1, then it is a composite number.
The factors of 276 are as follows:
1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
Therefore, since 276 is divisible by more than one and itself, the answer to the
question "Is 276 prime or composite?" is highlighted in blue below.
composite
Is 277 prime or composite?
OK. Now you know that 276 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.
