To determine if 1931 is a prime number or a composite number, we simply look at the factors for 1931.
If the factors of 1931 are only 1931 and 1, then we know that 1931 is a prime number. Otherwise, 1931 is a composite number.
To explain better, if 1931 is only divisible by 1 and 1931, then it is a prime number, and if 1931 is divisible by more than 1931 and 1, then it is a composite number.
The factors of 1931 are as follows:
