To determine if 2171 is a prime number or a composite number, we simply look at the factors for 2171.
If the factors of 2171 are only 2171 and 1, then we know that 2171 is a prime number. Otherwise, 2171 is a composite number.
To explain better, if 2171 is only divisible by 1 and 2171, then it is a prime number, and if 2171 is divisible by more than 2171 and 1, then it is a composite number.
The factors of 2171 are as follows:
1, 13, 167, 2171
Therefore, since 2171 is divisible by more than one and itself, the answer to the
question "Is 2171 prime or composite?" is highlighted in blue below.
composite
Is 2172 prime or composite?
