Given Input Data is 920, 636, 129

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

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 129 is 3 x 43

The above numbers do not have any common prime factor. So GCD is 1

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(920, 636) = 146280

GCD(920, 636) = ( 920 x 636 ) / 146280

GCD(920, 636) = 585120 / 146280

GCD(920, 636) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 129

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

LCM(4, 129) = 516

GCD(4, 129) = ( 4 x 129 ) / 516

GCD(4, 129) = 516 / 516

GCD(4, 129) = 1

GCD of 920, 636, 129 is 1
