DLXXXIV

DLXXXIV is the representation of the integer 584 in Roman numerals. It combines D (500), L (50), XXX (30) and IV (4) to yield 584 using standard additive and subtractive notation: 500 + 50 + 30 + (5 − 1) = 584. It may be read aloud as "five hundred eighty-four" or spelled letter-by-letter as "D L X X X I V."

As an integer, 584 is even and composite. Its prime factorization is 2^3 × 73, giving eight positive divisors: 1, 2, 4, 8, 73, 146, 292 and 584. The sum of all divisors is 1,110, and the sum of proper divisors is 526, so 584 is a deficient number (the sum of proper divisors is less than the number).

DLXXXIV can also appear as an ordinal or label in contexts that use Roman numerals, such as book chapters, municipal designations, inscriptions or plaques. In chronological terms it corresponds to the year 584 in the Julian calendar (AD 584) or, when interpreted differently, 584 BC. Usage conventions for Roman numerals vary historically and regionally; modern practice typically limits the use of numerals to specific formatting roles rather than everyday arithmetic.

As with other Roman numerals, DLXXXIV is part of a numeral system that remained influential in Europe for centuries and persists today in a variety of ceremonial, typographic and numbering applications.
