Given Input Data is 568, 580, 981, 909

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

Prime Factorization of 568 is 2 x 2 x 2 x 71

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 909 is 3 x 3 x 101

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(568, 580) = 82360

GCD(568, 580) = ( 568 x 580 ) / 82360

GCD(568, 580) = 329440 / 82360

GCD(568, 580) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 981

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

LCM(4, 981) = 3924

GCD(4, 981) = ( 4 x 981 ) / 3924

GCD(4, 981) = 3924 / 3924

GCD(4, 981) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 909

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

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

GCD(1, 909) = 909 / 909

GCD(1, 909) = 1

GCD of 568, 580, 981, 909 is 1
