Answer:
36
Explanation:
To find the L.C.M. of three given numbers, the easiest way of oral calculation, is to read out the table of the largest of them. And then check which of the multiples of the largest no. comes in the table of the other numbers. But that multiple should be the least one.
Like here, we have, 4, 9, and 3. Out of which, the largest number is 9. So,
9*1=9
9*2=18
9*3=27
9*4=36
9*5=45….
And so on.
Here, the first number in the table of 9, which also comes in the table of both 4 and 3, is 36.
So, 36 is the L.C.M. of 9, 4, and 3.
