To determine if 291 is a prime number or a composite number, we simply look at the factors for 291.
If the factors of 291 are only 291 and 1, then we know that 291 is a prime number. Otherwise, 291 is a composite number.
To explain better, if 291 is only divisible by 1 and 291, then it is a prime number, and if 291 is divisible by more than 291 and 1, then it is a composite number.
The factors of 291 are as follows:
1, 3, 97, 291
Therefore, since 291 is divisible by more than one and itself, the answer to the
question "Is 291 prime or composite?" is highlighted in blue below.
composite
Is 292 prime or composite?
OK. Now you know that 291 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.
