Find Least Common Multiple of 20 and 2 using LCM formula..

Answer

LCM( 20, 2 ) = 20

Explanation

The formula for finding LCM is

LCM (a, b) = \frac{a \cdot b}{GCD ( a , b )}

In this example we have: a = 20, b = 2 and GCD(20, 2) = 2.

LCM (20, 2) = \frac{20 \cdot 2}{GCD ( 20 , 2 )} = \frac{40}{2} = 20
