### Finding GCD of 621, 180, 216 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(621, 180) = 12420

GCD(621, 180) = ( 621 x 180 ) / 12420

GCD(621, 180) = 111780 / 12420

GCD(621, 180) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 216

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 216) = 216

GCD(9, 216) = ( 9 x 216 ) / 216

GCD(9, 216) = 1944 / 216

GCD(9, 216) = 9

GCD of 621, 180, 216 is 9
