To determine if 2168 is a prime number or a composite number, we simply look at the factors for 2168.
If the factors of 2168 are only 2168 and 1, then we know that 2168 is a prime number. Otherwise, 2168 is a composite number.
To explain better, if 2168 is only divisible by 1 and 2168, then it is a prime number, and if 2168 is divisible by more than 2168 and 1, then it is a composite number.
The factors of 2168 are as follows:
1, 2, 4, 8, 271, 542, 1084, 2168
Therefore, since 2168 is divisible by more than one and itself, the answer to the
question "Is 2168 prime or composite?" is highlighted in blue below.
