LCM( 700, 14700 ) = 14700
The formula for finding LCM is
$$ \text{LCM} (a, b) = \frac{ a \cdot b }{ \text{GCD}(a,b)} $$In this example we have: a = 700, b = 14700 and GCD(700, 14700) = 700.
$$ \text{LCM} (700, 14700) = \frac{ 700 \cdot 14700 }{ \text{GCD}(700,14700)} = \frac{ 10290000 }{ 700 } = 14700 $$
