Given Input Data is 957, 255, 635, 789

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

Prime Factorization of 957 is 3 x 11 x 29

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 635 is 5 x 127

Prime Factorization of 789 is 3 x 263

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(957, 255) = 81345

GCD(957, 255) = ( 957 x 255 ) / 81345

GCD(957, 255) = 244035 / 81345

GCD(957, 255) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 635

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

LCM(3, 635) = 1905

GCD(3, 635) = ( 3 x 635 ) / 1905

GCD(3, 635) = 1905 / 1905

GCD(3, 635) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 789

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

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

GCD(1, 789) = 789 / 789

GCD(1, 789) = 1

GCD of 957, 255, 635, 789 is 1
