LCM for 90 and 120 is 360.
Least Common Multiple (LCM) for 120 90 is 360.
The LCM is: 900
The Least Common Multiple (LCM) for 100 108 120 is 5,400.
The multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, etc ...The multiples of 30 are: 30, 60, 90, 120, 150, etc ...The multiples of 40 are: 40, 80, 120, 160, etc. ...The lowest multiple common to 20, 30, and 40 is 120, so the LCM = 120

The only Least Common Multiple (LCM) for 120 90 is 360.
Least Common Multiple (LCM) for 24 90 100 is 1,800.
360 - (90 + 100 + 120)...
The percentage reduction = (120 - 90) x 100 / 120 = 30 x 100/120 = 25%
