To determine if 2164 is a prime number or a composite number, we simply look at the factors for 2164.
If the factors of 2164 are only 2164 and 1, then we know that 2164 is a prime number. Otherwise, 2164 is a composite number.
To explain better, if 2164 is only divisible by 1 and 2164, then it is a prime number, and if 2164 is divisible by more than 2164 and 1, then it is a composite number.
The factors of 2164 are as follows:
1, 2, 4, 541, 1082, 2164
Therefore, since 2164 is divisible by more than one and itself, the answer to the
question "Is 2164 prime or composite?" is highlighted in blue below.
composite
Is 2165 prime or composite?
