For each instance of a variable included in the terms, compare the power of the variable in term one with the power of the variable in term two.

### How do you calculate least common denominator?

To find the least common denominator, list out the multiples of both denominators until you find the smallest multiple that is shared by both. Because 20 is the first shared multiple of 4 and 5, it must be the least common denominator for these two fractions.

**What is LCD in algebra?**

In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the lowest common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.

**Is LCM and LCD the same?**

The LCD and the LCM require the same math process: Finding a common multiple of two (or more) numbers. The only difference between LCD and LCM is that the LCD is the LCM in the denominator of a fraction. So, one could say that least common denominators are a special case of least common multiples.
