Question
Find Least Common Multiple of 45 and 60 using LCM formula..
Answer
LCM( 45, 60 ) = 180
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 = 45, b = 60 and GCD(45, 60) = 15.
$$ \text{LCM} (45, 60) = \frac{ 45 \cdot 60 }{ \text{GCD}(45,60)} = \frac{ 2700 }{ 15 } = 180 $$This page was created using
