Given Input Data is 910, 868, 78, 631

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

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 631 is 631

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(910, 868) = 56420

GCD(910, 868) = ( 910 x 868 ) / 56420

GCD(910, 868) = 789880 / 56420

GCD(910, 868) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 78

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

LCM(14, 78) = 546

GCD(14, 78) = ( 14 x 78 ) / 546

GCD(14, 78) = 1092 / 546

GCD(14, 78) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 631

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

LCM(2, 631) = 1262

GCD(2, 631) = ( 2 x 631 ) / 1262

GCD(2, 631) = 1262 / 1262

GCD(2, 631) = 1

GCD of 910, 868, 78, 631 is 1
