Finding GCD of 420, 388, 286 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(420, 388) = 40740
GCD(420, 388) = ( 420 x 388 ) / 40740
GCD(420, 388) = 162960 / 40740
GCD(420, 388) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 286
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 286) = 572
GCD(4, 286) = ( 4 x 286 ) / 572
GCD(4, 286) = 1144 / 572
GCD(4, 286) = 2
GCD of 420, 388, 286 is 2
