CLXXIV

CLXXIV is the Roman numeral for the integer 174. In standard notation it is formed by CL (150) plus XX (20) plus IV (4), yielding 174.

The symbols used are C=100, L=50, X=10, V=5, and I=1. Therefore CL contributes 150, XX contributes 20, and IV contributes 4. This numeral employs subtractive notation for four (IV) rather than an additive IIII, a convention common in classical inscriptions but not universal in all clocks.

174 is an even composite number with prime factorization 2 × 3 × 29. Its divisors include 1, 2, 3, 6, 29, 58, 87, and 174.

In historical dating, CLXXIV would be used to denote the year 174 CE (AD) or 174 BCE, depending on system. Roman numerals are still used today in certain contexts, such as on clock faces, monarchial regalia, film titles, and inscriptions.
