Given Input Data is 858, 902, 779, 479

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

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 902 is 2 x 11 x 41

Prime Factorization of 779 is 19 x 41

Prime Factorization of 479 is 479

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(858, 902) = 35178

GCD(858, 902) = ( 858 x 902 ) / 35178

GCD(858, 902) = 773916 / 35178

GCD(858, 902) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 779

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

LCM(22, 779) = 17138

GCD(22, 779) = ( 22 x 779 ) / 17138

GCD(22, 779) = 17138 / 17138

GCD(22, 779) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 479

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

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

GCD(1, 479) = 479 / 479

GCD(1, 479) = 1

GCD of 858, 902, 779, 479 is 1
