To determine if 1880 is a prime number or a composite number, we simply look at the factors for 1880.
If the factors of 1880 are only 1880 and 1, then we know that 1880 is a prime number. Otherwise, 1880 is a composite number.
To explain better, if 1880 is only divisible by 1 and 1880, then it is a prime number, and if 1880 is divisible by more than 1880 and 1, then it is a composite number.
The factors of 1880 are as follows:
1, 2, 4, 5, 8, 10, 20, 40, 47, 94, 188, 235, 376, 470, 940, 1880
Therefore, since 1880 is divisible by more than one and itself, the answer to the
question "Is 1880 prime or composite?" is highlighted in blue below.
composite
Is 1881 prime or composite?
