#### Explanation:

The Least Common Denominator (L.C.D) as you said, can be gotten from the Lowest Common Multiple (L.C.M) from of the two digits..

Hence we have for

Since

Hence the L.C.M for both digits are

Hence the L.C.D of

Though the L.C.D, is best explained using fractions, but what is given is just whole number..

To make it more crystal..

An example, Find the L.C.D of

Like i said it has to do with the Denominators, like making the denominators common..

We have

L.C.M of

L.C.M of

The one in red color is common in both digits, so we will just take one

Hope this helps!
