To determine if 2080 is a prime number or a composite number, we simply look at the factors for 2080.
If the factors of 2080 are only 2080 and 1, then we know that 2080 is a prime number. Otherwise, 2080 is a composite number.
To explain better, if 2080 is only divisible by 1 and 2080, then it is a prime number, and if 2080 is divisible by more than 2080 and 1, then it is a composite number.
The factors of 2080 are as follows:
1, 2, 4, 5, 8, 10, 13, 16, 20, 26, 32, 40, 52, 65, 80, 104, 130, 160, 208, 260, 416, 520, 1040, 2080
Therefore, since 2080 is divisible by more than one and itself, the answer to the
question "Is 2080 prime or composite?" is highlighted in blue below.
composite
Is 2081 prime or composite?
OK. Now you know that 2080 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
