To determine if 871 is a prime number or a composite number, we simply look at the factors for 871.
If the factors of 871 are only 871 and 1, then we know that 871 is a prime number. Otherwise, 871 is a composite number.
To explain better, if 871 is only divisible by 1 and 871, then it is a prime number, and if 871 is divisible by more than 871 and 1, then it is a composite number.
The factors of 871 are as follows:
1, 13, 67, 871
Therefore, since 871 is divisible by more than one and itself, the answer to the
question "Is 871 prime or composite?" is highlighted in blue below.
composite
Is 872 prime or composite?
OK. Now you know that 871 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.
