this may be very obvious but my textbook says:

3x(2x-1) and 2x-1

the LCM is 3x(2x-1) , I want to get the logic of this Thanks :)

A Lowest common multiple is the smallest number in which two numbers can both be divided by. 

In this situation you have one number (2X-1) and another number which is (3x) times as large.

this means 2x-1 is a factor of 3x(2x-1). 

In this case the LCM must be 3x(2x-1) as it is divisible by both.
