304 in Roman Numerals
Three hundred four is written CCCIV in Roman numerals. It uses the subtractive rule, where a smaller glyph placed before a larger one is taken away rather than added, which keeps the numeral short and is the part most people find fiddly.

Reading left to right, 304 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
C + C + C + IV = 100 + 100 + 100 + 4 = 304.

Frequently asked questions
How do you write 304 in Roman numerals?
Write 304 as CCCIV, combining C + C + C + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 304 not written CCCIIII?
CCCIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CCCIIII breaks that rule, which is why CCCIV is the only correct form.
What are 303 and 305 in Roman numerals?
303 is CCCIII and 305 is CCCV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is CCCIV broken down?
CCCIV breaks down as C (100), C (100), C (100), IV (4), so C + C + C + IV = 100 + 100 + 100 + 4 = 304.
