Editing Lowest common denominator (section)

==Practical uses==
The LCD has many practical uses, such as determining the number of objects of two different lengths necessary to align them in a row which starts and ends at the same place, such as in [[brickwork]], [[tile|tiling]], and [[tessellation]]. It is also useful in planning [[work schedule]]s with employees with ''y'' days off every ''x'' days.

In musical rhythm, the LCD is used in [[cross-rhythm]]s and [[polymeter]]s to determine the fewest notes necessary to [[count time]] given two or more [[metre (music)|metric]] divisions. For example, much African music is recorded in Western notation using {{music|time|12|8}} because each measure is divided by 4 and by 3, the LCD of which is 12.
