To determine if 2166 is a prime number or a composite number, we simply look at the factors for 2166.
If the factors of 2166 are only 2166 and 1, then we know that 2166 is a prime number. Otherwise, 2166 is a composite number.
To explain better, if 2166 is only divisible by 1 and 2166, then it is a prime number, and if 2166 is divisible by more than 2166 and 1, then it is a composite number.
The factors of 2166 are as follows:
1, 2, 3, 6, 19, 38, 57, 114, 361, 722, 1083, 2166
Therefore, since 2166 is divisible by more than one and itself, the answer to the
question "Is 2166 prime or composite?" is highlighted in blue below.
composite
Is 2167 prime or composite?
