Given Input Data is 606, 159, 270, 646

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

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 159 is 3 x 53

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 646 is 2 x 17 x 19

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(606, 159) = 32118

GCD(606, 159) = ( 606 x 159 ) / 32118

GCD(606, 159) = 96354 / 32118

GCD(606, 159) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 270

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

LCM(3, 270) = 270

GCD(3, 270) = ( 3 x 270 ) / 270

GCD(3, 270) = 810 / 270

GCD(3, 270) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 646

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

LCM(3, 646) = 1938

GCD(3, 646) = ( 3 x 646 ) / 1938

GCD(3, 646) = 1938 / 1938

GCD(3, 646) = 1

GCD of 606, 159, 270, 646 is 1
