Given Input Data is 858, 786, 811, 779

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 786 is 2 x 3 x 131

Prime Factorization of 811 is 811

Prime Factorization of 779 is 19 x 41

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, 786) = 112398

GCD(858, 786) = ( 858 x 786 ) / 112398

GCD(858, 786) = 674388 / 112398

GCD(858, 786) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 811

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

LCM(6, 811) = 4866

GCD(6, 811) = ( 6 x 811 ) / 4866

GCD(6, 811) = 4866 / 4866

GCD(6, 811) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 779

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

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

GCD(1, 779) = 779 / 779

GCD(1, 779) = 1

GCD of 858, 786, 811, 779 is 1
