Find Least Common Multiple of 3 and 7 using LCM formula..
Answer
LCM( 3, 7 ) = 21
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 = 7 and GCD(3, 7) = 1.
$$ \text{LCM} (3, 7) = \frac{ 3 \cdot 7 }{ \text{GCD}(3,7)} = \frac{ 21 }{ 1 } = 21 $$This page was created using
