CDXIV

414 is written CDXIV in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.

How it breaks down

CDXIV = 400 + 10 + 4 = 414
Group Value Subtraction Running total
CD 400 D − C 400
X 10 410
IV 4 V − I 414

Why the smaller symbol comes first

CDXIV uses subtractive notation in 2 places: CD means D minus C, or 400; IV means V minus I, or 4. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.

Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
