Given Input Data is 189, 474, 339, 136

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

Prime Factorization of 189 is 3 x 3 x 3 x 7

Prime Factorization of 474 is 2 x 3 x 79

Prime Factorization of 339 is 3 x 113

Prime Factorization of 136 is 2 x 2 x 2 x 17

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(189, 474) = 29862

GCD(189, 474) = ( 189 x 474 ) / 29862

GCD(189, 474) = 89586 / 29862

GCD(189, 474) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 339

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

LCM(3, 339) = 339

GCD(3, 339) = ( 3 x 339 ) / 339

GCD(3, 339) = 1017 / 339

GCD(3, 339) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 136

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

LCM(3, 136) = 408

GCD(3, 136) = ( 3 x 136 ) / 408

GCD(3, 136) = 408 / 408

GCD(3, 136) = 1

GCD of 189, 474, 339, 136 is 1
