504 in Roman Numerals
Five hundred four is written DIV in Roman numerals. It uses the subtractive rule, where a smaller glyph placed before a larger one is taken away rather than added, which keeps the numeral short and is the part most people find fiddly.

Frequently asked questions
How do you write 504 in Roman numerals?
Write 504 as DIV, combining D + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 504 not written DIIII?
DIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. DIIII breaks that rule, which is why DIV is the only correct form.
What are 503 and 505 in Roman numerals?
503 is DIII and 505 is DV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is DIV broken down?
DIV breaks down as D (500), IV (4), so D + IV = 500 + 4 = 504.
