Question
Find Least Common Multiple of 50 and 40 using LCM formula..
Answer
LCM( 50, 40 ) = 200
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 = 50, b = 40 and GCD(50, 40) = 10.
$$ \text{LCM} (50, 40) = \frac{ 50 \cdot 40 }{ \text{GCD}(50,40)} = \frac{ 2000 }{ 10 } = 200 $$This page was created using
