CCCLXXVII

CCCLXXVII is the Roman numeral for the number 377. It is formed by combining CCC (300) + LXX (70) + VII (7), illustrating the additive approach used in standard Roman numeral notation for mid-range values.

In mathematics, 377 is a composite number with prime factors 13 and 29 (377 = 13 × 29). It is also a Fibonacci number, appearing as the 14th term in the sequence that begins 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610.

In historical dating, 377 CE refers to a year in the late Roman Empire. During this period, the Visigoths crossed the Danube and sought asylum within the Roman Empire, a situation that contributed to tensions that culminated in the Battle of Adrianople in 378, where Emperor Valens was killed and the Gothic relationship with Rome shifted significantly.

Apart from its use as a numeral, CCCLXXVII may appear in lists, chapters, or titles that employ Roman numerals to denote order or year equivalents. Its mathematical properties (being a Fibonacci number and a composite) and its Roman-form construction are common points of reference in discussions of numbers and numeral systems.
