DCCCXXXI
831 in Roman numerals is DCCCXXXI.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which does not happen in this case.

Step-by-step conversion of 831:

1. D = 500 → represents hundreds.

2. CCC = 100 + 100 + 100 = 300 → C repeated 3 times.

3. XXX = 10 + 10 + 10 = 30 → X repeated 3 times.

4. I = 1 → represents units.

So, 500 + 300 + 30 + 1 = 831, or DCCCXXXI in Roman numeral form.
