To determine if 981 is a prime number or a composite number, we simply look at the factors for 981.
If the factors of 981 are only 981 and 1, then we know that 981 is a prime number. Otherwise, 981 is a composite number.
To explain better, if 981 is only divisible by 1 and 981, then it is a prime number, and if 981 is divisible by more than 981 and 1, then it is a composite number.
The factors of 981 are as follows:
1, 3, 9, 109, 327, 981
Therefore, since 981 is divisible by more than one and itself, the answer to the
question "Is 981 prime or composite?" is highlighted in blue below.
composite
Is 982 prime or composite?
OK. Now you know that 981 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.
