To determine if 7880 is a prime number or a composite number, we simply look at the factors for 7880.
If the factors of 7880 are only 7880 and 1, then we know that 7880 is a prime number. Otherwise, 7880 is a composite number.
To explain better, if 7880 is only divisible by 1 and 7880, then it is a prime number, and if 7880 is divisible by more than 7880 and 1, then it is a composite number.
The factors of 7880 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 197, 394, 788, 985, 1576, 1970, 3940, 7880
Therefore, since 7880 is divisible by more than one and itself, the answer to the
question "Is 7880 prime or composite?" is highlighted in blue below.
composite
Is 7881 prime or composite?
