To determine if 1912 is a prime number or a composite number, we simply look at the factors for 1912.
If the factors of 1912 are only 1912 and 1, then we know that 1912 is a prime number. Otherwise, 1912 is a composite number.
To explain better, if 1912 is only divisible by 1 and 1912, then it is a prime number, and if 1912 is divisible by more than 1912 and 1, then it is a composite number.
The factors of 1912 are as follows:
1, 2, 4, 8, 239, 478, 956, 1912
Therefore, since 1912 is divisible by more than one and itself, the answer to the
question "Is 1912 prime or composite?" is highlighted in blue below.
composite
Is 1913 prime or composite?
