To determine if 2078 is a prime number or a composite number, we simply look at the factors for 2078.
If the factors of 2078 are only 2078 and 1, then we know that 2078 is a prime number. Otherwise, 2078 is a composite number.
To explain better, if 2078 is only divisible by 1 and 2078, then it is a prime number, and if 2078 is divisible by more than 2078 and 1, then it is a composite number.
The factors of 2078 are as follows:
1, 2, 1039, 2078
Therefore, since 2078 is divisible by more than one and itself, the answer to the
question "Is 2078 prime or composite?" is highlighted in blue below.
composite
Is 2079 prime or composite?
