Quizplus · Accepted Answer

The least common denominator (LCD) is the least common multiple (LCM) of the denominators. The denominators are 8, 18, 9, and 14. The prime factorization of these numbers are 8 = $2^3$, 18 = $2 \times 3^2$, 9 = $3^2$, and 14 = $2 \times 7$. The LCM is $2^3 \times 3^2 \times 7 = 504$, which is the LCD.
