Question
Find Least Common Multiple of 16 and 20 using LCM formula..
Answer
LCM( 16, 20 ) = 80
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 = 16, b = 20 and GCD(16, 20) = 4.
$$ \text{LCM} (16, 20) = \frac{ 16 \cdot 20 }{ \text{GCD}(16,20)} = \frac{ 320 }{ 4 } = 80 $$This page was created using
