### Finding Lowest Common Denominator (LCD)

The lowest common denominator or least common

denominator (abbreviated LCD) is the least common

multiple of a set of fractions. It is the smallest number

that both denominators can divide by evenly.

**Example: The LCD of the fraction below is 36**

36 least common multiples of 12

and 18 is 36 or the smallest

number that both 12 and 18 can

divide by evenly (with no remainder.

These two fractions can know be added or subtracted
