Least Common Multiple (LCM) for 120 90 is 360.
Write out the multiples of each: 30, 60, 90, 120 40, 80, 120. 120 is the first that appears in both and this is your LCM
Multiples of 18: {18, 36, 54, 72, 90...}Multiples of 30: {30, 60, 90, 120, 150...}Therefore the LCM is 90.
The answer is 120.It is: 120
The LCM is: 120
Least Common Multiple (LCM) for 120 90 is 360.

Tough Question. The answer I got 380 but it is 360.
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
In order to have an LCM, there has to be two or more numbers. Some multiples of 30 are 60, 90, 120, etc.
The answer is 120.It is: 120
the LCM of 40 and 12 is 120.
