The LCM is: 108
The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least denominator for a number is itself.
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
