To determine if 2740 is a prime number or a composite number, we simply look at the factors for 2740.
If the factors of 2740 are only 2740 and 1, then we know that 2740 is a prime number. Otherwise, 2740 is a composite number.
To explain better, if 2740 is only divisible by 1 and 2740, then it is a prime number, and if 2740 is divisible by more than 2740 and 1, then it is a composite number.
The factors of 2740 are as follows:
1, 2, 4, 5, 10, 20, 137, 274, 548, 685, 1370, 2740
Therefore, since 2740 is divisible by more than one and itself, the answer to the
question "Is 2740 prime or composite?" is highlighted in blue below.
composite
Is 2741 prime or composite?
