How To Find The Least Common Denominator?

How do you find the LCD?

One way to find the least common denominator (LCD) of two or more fractions is by listing the factors of each denominator, which are all of the whole numbers that divide evenly into that number.

Then, identify the greatest common factor between the two denominators.

How do you find the lowest common denominator?
