To determine if 288 is a prime number or a composite number, we simply look at the factors for 288.
If the factors of 288 are only 288 and 1, then we know that 288 is a prime number. Otherwise, 288 is a composite number.
To explain better, if 288 is only divisible by 1 and 288, then it is a prime number, and if 288 is divisible by more than 288 and 1, then it is a composite number.
The factors of 288 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
Therefore, since 288 is divisible by more than one and itself, the answer to the
question "Is 288 prime or composite?" is highlighted in blue below.
composite
Is 289 prime or composite?
OK. Now you know that 288 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.
