To determine if 266 is a prime number or a composite number, we simply look at the factors for 266.
If the factors of 266 are only 266 and 1, then we know that 266 is a prime number. Otherwise, 266 is a composite number.
To explain better, if 266 is only divisible by 1 and 266, then it is a prime number, and if 266 is divisible by more than 266 and 1, then it is a composite number.
The factors of 266 are as follows:
1, 2, 7, 14, 19, 38, 133, 266
Therefore, since 266 is divisible by more than one and itself, the answer to the
question "Is 266 prime or composite?" is highlighted in blue below.
composite
Is 267 prime or composite?
OK. Now you know that 266 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.
