Given Input Data is 621, 180, 216

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 180 is 2 x 2 x 3 x 3 x 5

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Highest common occurrences in the given inputs are 3²

Multiplying them we get the GCD as 9

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
