CDXXVI
426 in Roman numerals is CDXXVI.

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 happens in this case.

Step-by-step conversion of 426:

1. CD = 500 - 100 = 400 → subtraction rule used.

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

3. V = 5 → represents units.

4. I = 1 → represents units.

So, 400 + 20 + 5 + 1 = 426, or CDXXVI in Roman numeral form.
