To determine if 1906 is a prime number or a composite number, we simply look at the factors for 1906.
If the factors of 1906 are only 1906 and 1, then we know that 1906 is a prime number. Otherwise, 1906 is a composite number.
To explain better, if 1906 is only divisible by 1 and 1906, then it is a prime number, and if 1906 is divisible by more than 1906 and 1, then it is a composite number.
The factors of 1906 are as follows:
1, 2, 953, 1906
Therefore, since 1906 is divisible by more than one and itself, the answer to the
question "Is 1906 prime or composite?" is highlighted in blue below.
composite
Is 1907 prime or composite?
