To determine if 1923 is a prime number or a composite number, we simply look at the factors for 1923.
If the factors of 1923 are only 1923 and 1, then we know that 1923 is a prime number. Otherwise, 1923 is a composite number.
To explain better, if 1923 is only divisible by 1 and 1923, then it is a prime number, and if 1923 is divisible by more than 1923 and 1, then it is a composite number.
The factors of 1923 are as follows:
1, 3, 641, 1923
Therefore, since 1923 is divisible by more than one and itself, the answer to the
question "Is 1923 prime or composite?" is highlighted in blue below.
composite
Is 1924 prime or composite?
