To determine if 2085 is a prime number or a composite number, we simply look at the factors for 2085.
If the factors of 2085 are only 2085 and 1, then we know that 2085 is a prime number. Otherwise, 2085 is a composite number.
To explain better, if 2085 is only divisible by 1 and 2085, then it is a prime number, and if 2085 is divisible by more than 2085 and 1, then it is a composite number.
The factors of 2085 are as follows:
1, 3, 5, 15, 139, 417, 695, 2085
Therefore, since 2085 is divisible by more than one and itself, the answer to the
question "Is 2085 prime or composite?" is highlighted in blue below.
composite
Is 2086 prime or composite?
