Least common denominator.

Used in fractions.

For example : 1/2 and 3/4

The fraction that has the lowest denominator, while still having an equivalent fraction is the LCD.

In this case it would be 2/4 and 3/4. Because 1/2 = 2/4, and the lowest common denominator between the two fractions is 4. Hope this helps ! :D

One common use is to add, subtract, or compare two fractions. Any common denominator can be used for this purpose - for example, just multiplying the denominators will work. But finding the least common denominator helps by letting you work with smaller numbers later, and requiring less work for the simplification of the resulting fraction.

LCD stands for Lowest or Least Common Denominator. It's just like the LCM (Least Common Multiple) and is used to make fractions suitable for addition and subtraction.
