To determine if 1910 is a prime number or a composite number, we simply look at the factors for 1910.
If the factors of 1910 are only 1910 and 1, then we know that 1910 is a prime number. Otherwise, 1910 is a composite number.
To explain better, if 1910 is only divisible by 1 and 1910, then it is a prime number, and if 1910 is divisible by more than 1910 and 1, then it is a composite number.
The factors of 1910 are as follows:
1, 2, 5, 10, 191, 382, 955, 1910
Therefore, since 1910 is divisible by more than one and itself, the answer to the
question "Is 1910 prime or composite?" is highlighted in blue below.
composite
Is 1911 prime or composite?
