104 in Roman Numerals
One hundred four is written CIV 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.

C + IV = 100 + 4 = 104.

Frequently asked questions
How do you write 104 in Roman numerals?
Write 104 as CIV, combining C + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 104 not written CIIII?
CIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CIIII breaks that rule, which is why CIV is the only correct form.
What are 103 and 105 in Roman numerals?
103 is CIII and 105 is CV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is CIV broken down?
CIV breaks down as C (100), IV (4), so C + IV = 100 + 4 = 104.
