The LCM of 3, 6 and 18 is 18. Other common multiples include 36 and 54.
18 is the answerThe LCM of these three numbers is 18.18
LCM=18=2*32 HCF(guess that is what u meant, highest common factor)=3 Possibilities: 3 and 18, 6 and 9, three or all of the numbers together. Note: 3 and 6 gives a LCM of 6 3 and 9 gives a LCM of 9 6 and 18 gives a HCF of 6 9 and 18 gives a HCF of 9 Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
The Least Common Multiple (LCM) for 18 3 6 is 18.
3: 3, 6, 9, ... 6: 6, 12, 18, ... 18: 18, 36, 54, ... The lcm(3, 6, 18) = 18, so the multiples of 18 are common multiples of all of them.
The LCM is 18.
The LCM is 18.
The LCM is 18
lcm(18, 9, 3) = 18.
The LCM of 3, 6 and 9 is 18.
HCF = 3... LCM = 18 !
The LCM is 18.
The LCM is 198.
