Question

HCF (8,36) =4,its LCM is

Thanks

Answer 1

Let the LCM be x, Now we know that , the product of two numbers= HCF*LCM, Therefore 8*36 =4*x Now x=(8*36)/4 X=72 Answer=72 is the LCM

Answer 2

To get the Least Common Multiple (LCM) of 8 and 36 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:

8:   222 ,
 36:   22 33 ,
LCM:   22233

The Least Common Multiple (LCM) is:   2 x 2 x 2 x 3 x 3 = 72
