To determine if 3880 is a prime number or a composite number, we simply look at the factors for 3880.
If the factors of 3880 are only 3880 and 1, then we know that 3880 is a prime number. Otherwise, 3880 is a composite number.
To explain better, if 3880 is only divisible by 1 and 3880, then it is a prime number, and if 3880 is divisible by more than 3880 and 1, then it is a composite number.
The factors of 3880 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 97, 194, 388, 485, 776, 970, 1940, 3880
Therefore, since 3880 is divisible by more than one and itself, the answer to the
question "Is 3880 prime or composite?" is highlighted in blue below.
composite
Is 3881 prime or composite?
