To determine if 681 is a prime number or a composite number, we simply look at the factors for 681.
If the factors of 681 are only 681 and 1, then we know that 681 is a prime number. Otherwise, 681 is a composite number.
To explain better, if 681 is only divisible by 1 and 681, then it is a prime number, and if 681 is divisible by more than 681 and 1, then it is a composite number.
The factors of 681 are as follows:
1, 3, 227, 681
Therefore, since 681 is divisible by more than one and itself, the answer to the
question "Is 681 prime or composite?" is highlighted in blue below.
composite
Is 682 prime or composite?
OK. Now you know that 681 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.
