To determine if 2055 is a prime number or a composite number, we simply look at the factors for 2055.
If the factors of 2055 are only 2055 and 1, then we know that 2055 is a prime number. Otherwise, 2055 is a composite number.
To explain better, if 2055 is only divisible by 1 and 2055, then it is a prime number, and if 2055 is divisible by more than 2055 and 1, then it is a composite number.
The factors of 2055 are as follows:
1, 3, 5, 15, 137, 411, 685, 2055
Therefore, since 2055 is divisible by more than one and itself, the answer to the
question "Is 2055 prime or composite?" is highlighted in blue below.
composite
Is 2056 prime or composite?
