Given Input Data is 568, 860, 557, 847

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 860 is 2 x 2 x 5 x 43

Prime Factorization of 557 is 557

Prime Factorization of 847 is 7 x 11 x 11

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, 860) = 122120

GCD(568, 860) = ( 568 x 860 ) / 122120

GCD(568, 860) = 488480 / 122120

GCD(568, 860) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 557

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

LCM(4, 557) = 2228

GCD(4, 557) = ( 4 x 557 ) / 2228

GCD(4, 557) = 2228 / 2228

GCD(4, 557) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 847

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

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

GCD(1, 847) = 847 / 847

GCD(1, 847) = 1

GCD of 568, 860, 557, 847 is 1
