To determine if 2685 is a prime number or a composite number, we simply look at the factors for 2685.
If the factors of 2685 are only 2685 and 1, then we know that 2685 is a prime number. Otherwise, 2685 is a composite number.
To explain better, if 2685 is only divisible by 1 and 2685, then it is a prime number, and if 2685 is divisible by more than 2685 and 1, then it is a composite number.
The factors of 2685 are as follows:
1, 3, 5, 15, 179, 537, 895, 2685
Therefore, since 2685 is divisible by more than one and itself, the answer to the
question "Is 2685 prime or composite?" is highlighted in blue below.
