To determine if 284 is a prime number or a composite number, we simply look at the factors for 284.
If the factors of 284 are only 284 and 1, then we know that 284 is a prime number. Otherwise, 284 is a composite number.
To explain better, if 284 is only divisible by 1 and 284, then it is a prime number, and if 284 is divisible by more than 284 and 1, then it is a composite number.
The factors of 284 are as follows:
1, 2, 4, 71, 142, 284
Therefore, since 284 is divisible by more than one and itself, the answer to the
question "Is 284 prime or composite?" is highlighted in blue below.
composite
Is 285 prime or composite?
OK. Now you know that 284 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.
