To determine if 4080 is a prime number or a composite number, we simply look at the factors for 4080.
If the factors of 4080 are only 4080 and 1, then we know that 4080 is a prime number. Otherwise, 4080 is a composite number.
To explain better, if 4080 is only divisible by 1 and 4080, then it is a prime number, and if 4080 is divisible by more than 4080 and 1, then it is a composite number.
The factors of 4080 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 17, 20, 24, 30, 34, 40, 48, 51, 60, 68, 80, 85, 102, 120, 136, 170, 204, 240, 255, 272, 340, 408, 510, 680, 816, 1020, 1360, 2040, 4080
Therefore, since 4080 is divisible by more than one and itself, the answer to the
question "Is 4080 prime or composite?" is highlighted in blue below.
composite
Is 4081 prime or composite?
