How to get the LCD easily:

Three numbers are shown below.

3      3      3
4     14     7

Now. The last thing you need to do is find their exact alike denominator using LCD. (at where they have the same number is where i will stop.)

4=4, 8 ,12, 16, 20, 24, 28................
14=14, 28..........
7=7, 14, 21, 28................

So 28 is their common denominator. Or you can do it this the most easiest way:

These are the 3 numbers again. all you have to do is to multiply those 2 lesser numbers into the exact amount they would be with the biggest denominator:

4 x 7= 28

so they already have the same denominator because in these second one you just needed to multiply the lower number with the second lower number to be equal LCD.
