To determine if 7871 is a prime number or a composite number, we simply look at the factors for 7871.
If the factors of 7871 are only 7871 and 1, then we know that 7871 is a prime number. Otherwise, 7871 is a composite number.
To explain better, if 7871 is only divisible by 1 and 7871, then it is a prime number, and if 7871 is divisible by more than 7871 and 1, then it is a composite number.
The factors of 7871 are as follows:
1, 17, 463, 7871
Therefore, since 7871 is divisible by more than one and itself, the answer to the
question "Is 7871 prime or composite?" is highlighted in blue below.
