## How can factors help you find a common denominator?

**They are:**

- List the multiples for each number.
- Look at the lists you’ve made.
- Look for the smallest underlined number (least common multiple, or LCM).
- Multiply the numerator and denominator of each fraction by the factor that it would take to get to your common denominator.

## What is the common denominator of 5 and 8?

You need to know the least common denominator (LCD) of 5 and 8 if you want to add or subtract two fractions with 5 and 8 as denominators. The least common denominator, also called lowest common denominator (LCD), of 5 and 8 is 40.

## What fraction is bigger?

To compare fractions with unlike denominators convert them to equivalent fractions with the same denominator. Compare fractions: If denominators are the same you can compare the numerators. The fraction with the bigger numerator is the larger fraction.

## What is the least common denominator of 5 and 6?

## What is the fastest way to find the LCD?

**Here are the steps to follow:**

- Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).
- Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.
- Then add (or subtract) the fractions, as we wish!
