To determine if 1831 is a prime number or a composite number, we simply look at the factors for 1831.
If the factors of 1831 are only 1831 and 1, then we know that 1831 is a prime number. Otherwise, 1831 is a composite number.
To explain better, if 1831 is only divisible by 1 and 1831, then it is a prime number, and if 1831 is divisible by more than 1831 and 1, then it is a composite number.
The factors of 1831 are as follows:
