CDLXIII

CDLXIII is the Roman numeral representing the integer 463. It is formed by the combination CD for 400, LX for 60, and III for 3, reflecting the subtractive notation in which a smaller value placed before a larger one indicates subtraction. The sum of these parts yields 463, illustrating how Roman numerals encode numbers through additive and subtractive principles.

In mathematical terms, 463 is a prime number and is odd. In other numeral systems, it is written as binary 111001111 and hexadecimal 1CF. In decimal notation, it sits between 462 and 464. Its prime status means it has no positive divisors other than 1 and itself.

Historically and culturally, CDLXIII can denote the year 463 CE (AD) in chronologies and inscriptions. Roman numerals continue to appear in various modern contexts, such as on clock faces, in the numbering of chapters or volumes, on monuments, or in film and literary sequel conventions. When encountered, CDLXIII signals a traditional, Latin-derived method of dating or labeling, typical of classical studies and certain archival practices.
