To determine if 2040 is a prime number or a composite number, we simply look at the factors for 2040.
If the factors of 2040 are only 2040 and 1, then we know that 2040 is a prime number. Otherwise, 2040 is a composite number.
To explain better, if 2040 is only divisible by 1 and 2040, then it is a prime number, and if 2040 is divisible by more than 2040 and 1, then it is a composite number.
The factors of 2040 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 17, 20, 24, 30, 34, 40, 51, 60, 68, 85, 102, 120, 136, 170, 204, 255, 340, 408, 510, 680, 1020, 2040
Therefore, since 2040 is divisible by more than one and itself, the answer to the
question "Is 2040 prime or composite?" is highlighted in blue below.
composite
Is 2041 prime or composite?
