To determine if 3080 is a prime number or a composite number, we simply look at the factors for 3080.
If the factors of 3080 are only 3080 and 1, then we know that 3080 is a prime number. Otherwise, 3080 is a composite number.
To explain better, if 3080 is only divisible by 1 and 3080, then it is a prime number, and if 3080 is divisible by more than 3080 and 1, then it is a composite number.
The factors of 3080 are as follows:
1, 2, 4, 5, 7, 8, 10, 11, 14, 20, 22, 28, 35, 40, 44, 55, 56, 70, 77, 88, 110, 140, 154, 220, 280, 308, 385, 440, 616, 770, 1540, 3080
Therefore, since 3080 is divisible by more than one and itself, the answer to the
question "Is 3080 prime or composite?" is highlighted in blue below.
composite
Is 3081 prime or composite?
