Question
Find Least Common Multiple of 8 and 10 using LCM formula..
Answer
LCM( 8, 10 ) = 40
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 = 8, b = 10 and GCD(8, 10) = 2.
$$ \text{LCM} (8, 10) = \frac{ 8 \cdot 10 }{ \text{GCD}(8,10)} = \frac{ 80 }{ 2 } = 40 $$This page was created using
