How do you write 458 in Roman numerals?
Write 458 as CDLVIII, combining CD + L + V + I + I + I. Start from the largest value that fits and work down until nothing is left over.
Why is 458 not written CCCCLVIII?
CDLVIII uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CCCCLVIII breaks that rule, which is why CDLVIII is the only correct form.
