174 in Roman Numerals
One hundred seventy-four is written CLXXIV 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, 174 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
C + L + X + X + IV = 100 + 50 + 10 + 10 + 4 = 174.

Frequently asked questions
How do you write 174 in Roman numerals?
Write 174 as CLXXIV, combining C + L + X + X + IV. Start from the largest value that fits and work down until nothing is left over.
Why is 174 not written CLXXIIII?
CLXXIV uses the subtractive rule: a smaller symbol placed before a larger one is taken away, so you never repeat a symbol four times. CLXXIIII breaks that rule, which is why CLXXIV is the only correct form.
What are 173 and 175 in Roman numerals?
173 is CLXXIII and 175 is CLXXV. Neighbouring numbers often change length in surprising ways, which is why each has its own page.
How is CLXXIV broken down?
CLXXIV breaks down as C (100), L (50), X (10), X (10), IV (4), so C + L + X + X + IV = 100 + 50 + 10 + 10 + 4 = 174.
