To determine if 8080 is a prime number or a composite number, we simply look at the factors for 8080.
If the factors of 8080 are only 8080 and 1, then we know that 8080 is a prime number. Otherwise, 8080 is a composite number.
To explain better, if 8080 is only divisible by 1 and 8080, then it is a prime number, and if 8080 is divisible by more than 8080 and 1, then it is a composite number.
The factors of 8080 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 101, 202, 404, 505, 808, 1010, 1616, 2020, 4040, 8080
Therefore, since 8080 is divisible by more than one and itself, the answer to the
question "Is 8080 prime or composite?" is highlighted in blue below.
composite
Is 8081 prime or composite?
