LCM( 5, 2, 2, 2 ) = 10
Write down multiples of each number until you find the first common multiple:
The multipliers of 5 are: 5, 10, 15, . . .
The multipliers of 2 are: 2, 4, 6, 8, 10, 12, . . .
The multipliers of 2 are: 2, 4, 6, 8, 10, 12, . . .
The multipliers of 2 are: 2, 4, 6, 8, 10, 12, . . .
We can see that:
