464 in Roman Numerals = CDLXIV
Four hundred sixty-four is written CDLXIV in Roman numerals. The subtractive rule works twice in CDLXIV, in CD for 400 and IV for 4: a smaller glyph placed before a larger one is taken away rather than added, which keeps CDLXIV shorter than stacking strokes would.

The shape of CDLXIV
- Written out, CDLXIV runs 6 characters, against 7 for 463 (CDLXIII) and 5 for 465 (CDLXV).
- CDLXIV works 2 subtractions at once, CD and IV, which is why it comes out shorter than a stroke-for-stroke spelling of 464 would.
- Every number from 400 to 499 opens with CD, so it is the LXIV after CD that marks 464 out as 64 past 400.
- CDLXIV uses 6 different symbols and repeats none of them: one appearance each.

Frequently asked questions
How do you write 464 in Roman numerals?
Write 464 as CDLXIV, combining CD + L + X + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 464 not written CDLXIIII?
CDLXIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CDLXIIII breaks that rule, which is why CDLXIV is the only correct form.
What are 463 and 465 in Roman numerals?
463 is CDLXIII and 465 is CDLXV. Neighbouring numbers often change length in surprising ways, and the complete charts list every value in order, so the rows either side show both at a glance.
How is CDLXIV broken down?
CDLXIV breaks down as CD (400), L (50), X (10), IV (4), so CD + L + X + IV = 400 + 50 + 10 + 4 = 464.
