20, 40 and 60
20, 40, 60
90, 180, 270
multiples of 10- 10,20,30,40,50,60.... Multiples of 12- 12, 24, 36, 48, 60..... Answer-60
3,6,9,12,15,18,21,24,27,30 and so on but these are the first ten multiples of three
They are 10 and any multiples of 10
The LCM is: 210
The least common multiple of 6 and 10 is 30. Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60 and so on. Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 and so on. Here 30 and 60 are common multiples in the first ten multiples. But, 30 is the smallest so LCM is 30. If we continue to write more multiples we will find more common multiples, but the least common is only one.
You need at least two numbers to find an LCM.
9 is.
LCM(3, 10) = 30.
The Least Common Multiple (LCM) for 2 3 10 is 30.
