Given Input Data is 442, 697, 618, 399

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

Prime Factorization of 442 is 2 x 13 x 17

Prime Factorization of 697 is 17 x 41

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 399 is 3 x 7 x 19

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(442, 697) = 18122

GCD(442, 697) = ( 442 x 697 ) / 18122

GCD(442, 697) = 308074 / 18122

GCD(442, 697) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 618

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

LCM(17, 618) = 10506

GCD(17, 618) = ( 17 x 618 ) / 10506

GCD(17, 618) = 10506 / 10506

GCD(17, 618) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 399

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

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

GCD(1, 399) = 399 / 399

GCD(1, 399) = 1

GCD of 442, 697, 618, 399 is 1
