Given Input Data is 427, 476, 618

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

Prime Factorization of 427 is 7 x 61

Prime Factorization of 476 is 2 x 2 x 7 x 17

Prime Factorization of 618 is 2 x 3 x 103

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(427, 476) = 29036

GCD(427, 476) = ( 427 x 476 ) / 29036

GCD(427, 476) = 203252 / 29036

GCD(427, 476) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 618

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

LCM(7, 618) = 4326

GCD(7, 618) = ( 7 x 618 ) / 4326

GCD(7, 618) = 4326 / 4326

GCD(7, 618) = 1

GCD of 427, 476, 618 is 1
