How to write 580 in Roman numerals, step by step
Roman numerals are built from largest value to smallest. Split 580 into place values first: 500 + 50 + 30.
Now swap each part for its symbols: 500 becomes D, 50 becomes L, 30 becomes XXX. Written together that is DLXXX.
No subtraction is needed here, so the symbols are simply added in descending order.
- 500 = D (D is 500)
- 50 = L (L is 50)
- 30 = XXX (X is 10, written 3 times)
Is DLXXX written correctly?
Yes. DLXXX is the standard modern form of 580. A valid Roman numeral never repeats a symbol more than three times in a row, never repeats V, L or D at all, and only ever subtracts I, X or C, and only from the next two larger symbols.
Those rules are what keeps a number to a single accepted spelling, so a reader never has to guess.
How to type DLXXX on a keyboard

Unicode also contains dedicated Roman numeral characters such as Ⅰ, Ⅴ, Ⅹ, Ⅼ, Ⅽ, Ⅾ and Ⅿ. They exist for typesetting East Asian text and they look almost identical, but search engines, spell checkers and screen readers handle the plain letters better, so the letters are usually the right choice.
Where you will see DLXXX
Numbers of this size turn up as chapter and page numbers in front matter, as list levels in outlines, as monarch and pope regnal numbers, and in the names of recurring events such as Super Bowl finals.
If you are using DLXXX in a document, keep it in capitals. Lowercase roman numerals (dlxxx) are conventionally reserved for preliminary page numbering and sub-lists.
