Given Input Data is 685, 630, 556, 150

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

Prime Factorization of 685 is 5 x 137

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 556 is 2 x 2 x 139

Prime Factorization of 150 is 2 x 3 x 5 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(685, 630) = 86310

GCD(685, 630) = ( 685 x 630 ) / 86310

GCD(685, 630) = 431550 / 86310

GCD(685, 630) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 556

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

LCM(5, 556) = 2780

GCD(5, 556) = ( 5 x 556 ) / 2780

GCD(5, 556) = 2780 / 2780

GCD(5, 556) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 150

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

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

GCD(1, 150) = 150 / 150

GCD(1, 150) = 1

GCD of 685, 630, 556, 150 is 1
