DCLXXI
671 in Roman numerals is DCLXXI.

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 671:

1. D = 500 → represents hundreds.

2. C = 100 → represents hundreds.

3. L = 50 → represents tens.

4. XX = 10 + 10 = 20 → X repeated 2 times.

5. I = 1 → represents units.

So, 500 + 100 + 50 + 20 + 1 = 671, or DCLXXI in Roman numeral form.
