Find Least Common Multiple of 12 and 20 using LCM formula..
Answer
LCM( 12, 20 ) = 60
Explanation
The formula for finding LCM is
$$ \text{LCM} (a, b) = \frac{ a \cdot b }{ \text{GCD}(a,b)} $$In this example we have: a = 12, b = 20 and GCD(12, 20) = 4.
$$ \text{LCM} (12, 20) = \frac{ 12 \cdot 20 }{ \text{GCD}(12,20)} = \frac{ 240 }{ 4 } = 60 $$This page was created using
