Question
Find Least Common Multiple of 35 and 21 using LCM formula..
Answer
LCM( 35, 21 ) = 105
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 = 35, b = 21 and GCD(35, 21) = 7.
$$ \text{LCM} (35, 21) = \frac{ 35 \cdot 21 }{ \text{GCD}(35,21)} = \frac{ 735 }{ 7 } = 105 $$This page was created using
