Frequently asked questions
How do you write 477 in Roman numerals?
Write 477 as CDLXXVII, combining CD + L + X + X + V + I + I. Start from the largest value that fits and work down until nothing is left over.

CDLXXVII is 477, spoken as "four hundred seventy-seven". The numeral is read as the single value 477, not as its separate letters.
