To determine if 3040 is a prime number or a composite number, we simply look at the factors for 3040.
If the factors of 3040 are only 3040 and 1, then we know that 3040 is a prime number. Otherwise, 3040 is a composite number.
To explain better, if 3040 is only divisible by 1 and 3040, then it is a prime number, and if 3040 is divisible by more than 3040 and 1, then it is a composite number.
The factors of 3040 are as follows:
1, 2, 4, 5, 8, 10, 16, 19, 20, 32, 38, 40, 76, 80, 95, 152, 160, 190, 304, 380, 608, 760, 1520, 3040
Therefore, since 3040 is divisible by more than one and itself, the answer to the
question "Is 3040 prime or composite?" is highlighted in blue below.
composite
Is 3041 prime or composite?
