CCCXXVIII

CCCXXVIII is the Roman numeral for the number 328. It is formed from CCC (300) plus XX (20) plus VIII (8), representing additive notation rather than subtractive notation (there are no combining forms like IV or IX here). The arrangement illustrates the standard use of the symbols C (100), X (10), and V/I (5/1) to express a value through repetition and addition.

328 is an even, composite integer. Its prime factorization is 2^3 × 41, and its positive divisors are 1, 2, 4, 8, 41, 82, 164, and 328.

In usage, CCCXXVIII can appear in contexts that require Roman numerals—on monuments, clocks, book chapter headings, or historical timelines. It may denote the year 328 CE (or AD) in a chronology, though the specific historical events associated with that year depend on the historical record rather than the numeral itself.

In modern contexts, Roman numerals remain common for stylistic, archival, or ceremonial purposes rather than everyday counting. CCCXXVIII serves as a straightforward example of a non-subtractive Roman numeral representing a mid-range quantity.
