how to find the LCD for 11x/yz^2, 8x/y^2z?

I know the answer is yz^2 but how do you get that.
can you plzz plzz explain..... this it is really important..... thnx ...... a lot..

• math -

Look at the denominators, and find the individual factors:

11x/(yz^2): y*z^2
8x/(y^2z): y^2*z

The greatest power of y is y^2. The greatest power of z is z^2.

Now multiply the greatest powers to find the LCD.

The LCD should actually be y^2*z^2.
