To determine if 2119 is a prime number or a composite number, we simply look at the factors for 2119.
If the factors of 2119 are only 2119 and 1, then we know that 2119 is a prime number. Otherwise, 2119 is a composite number.
To explain better, if 2119 is only divisible by 1 and 2119, then it is a prime number, and if 2119 is divisible by more than 2119 and 1, then it is a composite number.
The factors of 2119 are as follows:
1, 13, 163, 2119
Therefore, since 2119 is divisible by more than one and itself, the answer to the
question "Is 2119 prime or composite?" is highlighted in blue below.
composite
Is 2120 prime or composite?
