To determine if 281 is a prime number or a composite number, we simply look at the factors for 281.
If the factors of 281 are only 281 and 1, then we know that 281 is a prime number. Otherwise, 281 is a composite number.
To explain better, if 281 is only divisible by 1 and 281, then it is a prime number, and if 281 is divisible by more than 281 and 1, then it is a composite number.
The factors of 281 are as follows:
1, 281
Therefore, since 281 is divisible by only one and itself, the answer to the
question "Is 281 prime or composite?" is highlighted in blue below.
prime
Is 282 prime or composite?
OK. Now you know that 281 is a prime 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.
