Find Least Common Multiple of 3 and 9 using LCM formula..
Answer
LCM( 3, 9 ) = 9
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 = 3, b = 9 and GCD(3, 9) = 3.
$$ \text{LCM} (3, 9) = \frac{ 3 \cdot 9 }{ \text{GCD}(3,9)} = \frac{ 27 }{ 3 } = 9 $$This page was created using
