Given Input Data is 777, 455, 872, 798

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

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 872 is 2 x 2 x 2 x 109

Prime Factorization of 798 is 2 x 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(777, 455) = 50505

GCD(777, 455) = ( 777 x 455 ) / 50505

GCD(777, 455) = 353535 / 50505

GCD(777, 455) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 872

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

LCM(7, 872) = 6104

GCD(7, 872) = ( 7 x 872 ) / 6104

GCD(7, 872) = 6104 / 6104

GCD(7, 872) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 798

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

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

GCD(1, 798) = 798 / 798

GCD(1, 798) = 1

GCD of 777, 455, 872, 798 is 1
