Given Input Data is 789, 195, 428, 160

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

Prime Factorization of 789 is 3 x 263

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

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(789, 195) = 51285

GCD(789, 195) = ( 789 x 195 ) / 51285

GCD(789, 195) = 153855 / 51285

GCD(789, 195) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 428

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

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

GCD(3, 428) = 1284 / 1284

GCD(3, 428) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 160

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

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

GCD(1, 160) = 160 / 160

GCD(1, 160) = 1

GCD of 789, 195, 428, 160 is 1
