To determine if 7040 is a prime number or a composite number, we simply look at the factors for 7040.
If the factors of 7040 are only 7040 and 1, then we know that 7040 is a prime number. Otherwise, 7040 is a composite number.
To explain better, if 7040 is only divisible by 1 and 7040, then it is a prime number, and if 7040 is divisible by more than 7040 and 1, then it is a composite number.
The factors of 7040 are as follows:
1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 32, 40, 44, 55, 64, 80, 88, 110, 128, 160, 176, 220, 320, 352, 440, 640, 704, 880, 1408, 1760, 3520, 7040
Therefore, since 7040 is divisible by more than one and itself, the answer to the
question "Is 7040 prime or composite?" is highlighted in blue below.
composite
Is 7041 prime or composite?
