Given Input Data is 560, 970, 27, 861

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

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 x 7

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 861 is 3 x 7 x 41

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(560, 970) = 54320

GCD(560, 970) = ( 560 x 970 ) / 54320

GCD(560, 970) = 543200 / 54320

GCD(560, 970) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 27

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

LCM(10, 27) = 270

GCD(10, 27) = ( 10 x 27 ) / 270

GCD(10, 27) = 270 / 270

GCD(10, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 560, 970, 27, 861 is 1
