To determine if 1929 is a prime number or a composite number, we simply look at the factors for 1929.
If the factors of 1929 are only 1929 and 1, then we know that 1929 is a prime number. Otherwise, 1929 is a composite number.
To explain better, if 1929 is only divisible by 1 and 1929, then it is a prime number, and if 1929 is divisible by more than 1929 and 1, then it is a composite number.
The factors of 1929 are as follows:
