Arabic to Roman Numeral Converter

Roman Numeral
MDCLXXX
1,680 in Roman numerals is MDCLXXX.

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 1,680:

1. M = 1,000 → represents thousands.

2. D = 500 → represents hundreds.

3. C = 100 → represents hundreds.

4. L = 50 → represents tens.

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

So, 1,000 + 500 + 100 + 50 + 30 = 1,680, or MDCLXXX in Roman numeral form.
