How It Works
The Least Common Denominator (LCD) is simply the Least Common Multiple (LCM) of all the denominators in a set of fractions.
Why find the LCD?
- It is required to add or subtract fractions with different denominators.
- It helps in comparing which fraction is larger.
- It keeps the numbers as small as possible, making math easier.
