To determine if 265 is a prime number or a composite number, we simply look at the factors for 265.
If the factors of 265 are only 265 and 1, then we know that 265 is a prime number. Otherwise, 265 is a composite number.
To explain better, if 265 is only divisible by 1 and 265, then it is a prime number, and if 265 is divisible by more than 265 and 1, then it is a composite number.
The factors of 265 are as follows:
1, 5, 53, 265
Therefore, since 265 is divisible by more than one and itself, the answer to the
question "Is 265 prime or composite?" is highlighted in blue below.
composite
Is 266 prime or composite?
OK. Now you know that 265 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.
