Finding GCD of 14, 56, 20 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(14, 56) = 56
GCD(14, 56) = ( 14 x 56 ) / 56
GCD(14, 56) = 784 / 56
GCD(14, 56) = 14
Step2:
Here we consider the GCD from the above i.e. 14 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(14, 20) = 140
GCD(14, 20) = ( 14 x 20 ) / 140
GCD(14, 20) = 280 / 140
GCD(14, 20) = 2
GCD of 14, 56, 20 is 2
