To determine if 287 is a prime number or a composite number, we simply look at the factors for 287.
If the factors of 287 are only 287 and 1, then we know that 287 is a prime number. Otherwise, 287 is a composite number.
To explain better, if 287 is only divisible by 1 and 287, then it is a prime number, and if 287 is divisible by more than 287 and 1, then it is a composite number.
The factors of 287 are as follows:
1, 7, 41, 287
Therefore, since 287 is divisible by more than one and itself, the answer to the
question "Is 287 prime or composite?" is highlighted in blue below.
composite
Is 288 prime or composite?
OK. Now you know that 287 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.
