sum of two no. is 132 and their lcm is 216:

1)Find the no.

2)find the cuberoot of the lcm in 1)

(1)  As the L.C.M. of the numbers is  216,  so both numbers must be a factor of  216.

First number  =   ,  second number  =   .

Where  a  and  b  are factors of  216.

Now,  first number  +  second number  =  132

By heart and trial method such that  L.C.M.  of both numbers is  216,  a =9  and  b = 2.

Hence,  numbers are  24  and  108.
