Finding the Lowest Common Denominator
Finding the Lowest Common Denominator is a skill on Pengi from Lesson 3: Lowest Common Denominator in Yoshiwara Elementary Algebra.
Key Concepts
Property The lowest common denominator (LCD) for two or more algebraic fractions is the simplest algebraic expression that is a multiple of each denominator. To find the LCD:.
1. Factor each denominator completely. 2. For each factor, include the most copies of that factor that appears in any single denominator. 3. Multiply together the factors of the LCD.
Examples The LCD for $\frac{1}{6a^2b}$ and $\frac{5}{9ab^3}$ is $18a^2b^3$. We need factors of $2 \cdot 3^2 \cdot a^2 \cdot b^3$.
