# FAQ: Math How To Get The Lcd?

## How do you find the LCD on a calculator?

How to Find LCD? In order to find the LCD, firstly we convert all integers and mixed fractions into fractions. Then we find the LCM of the denominators. The result is the LCD and each fraction should be written as an equivalent fraction with the same LCD.

## How do you find the lowest common denominator?

To find the lowest common denominator, we see if the larger denominator (20) can be divided by the smaller denominator (4). We then need to work out what we need to multiply the 4 by, to make 20 (this is 5). Therefore, we multiply 1/4 by 5, so that it becomes 5/20. You can then add 5/20 and 3/20 which makes 8/20.
