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.
