Given Input Data is 156, 570, 940, 195

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

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 940 is 2 x 2 x 5 x 47

Prime Factorization of 195 is 3 x 5 x 13

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(156, 570) = 14820

GCD(156, 570) = ( 156 x 570 ) / 14820

GCD(156, 570) = 88920 / 14820

GCD(156, 570) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 940

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

LCM(6, 940) = 2820

GCD(6, 940) = ( 6 x 940 ) / 2820

GCD(6, 940) = 5640 / 2820

GCD(6, 940) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 195

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

LCM(2, 195) = 390

GCD(2, 195) = ( 2 x 195 ) / 390

GCD(2, 195) = 390 / 390

GCD(2, 195) = 1

GCD of 156, 570, 940, 195 is 1
