CCCLXIX

CCCLXIX is the Roman numeral that represents the integer 369. It is composed of CCC (300) plus LX (60) plus IX (9). This arrangement reflects the additive principle of Roman numerals, where symbols placed from left to right are summed to yield the total.

In historical practice, CCCLXIX may appear as a year designation in sources that use Roman numerals, such as inscriptions or chronicles dating events to 369 CE or 369 BCE. It also occurs in contexts that employ Roman numerals for lists, chapters, monarchs, or catalog numbers.

Mathematically, 369 is a composite number with prime factorization 3^2 × 41. Its digits sum to 18, making the number divisible by 9 and by 3; it is not prime, not a power, and not a perfect square (it lies between 361 and 400).

Beyond pure numerals, CCCLXIX may appear in branding, edition numbers, or navigational labels in systems that historically use Roman numerals. As with other numerals, its value is understood in modern usage to be 369, serving mainly as a representation rather than a standalone concept.
