Given Input Data is 654, 927, 847, 685

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

Prime Factorization of 654 is 2 x 3 x 109

Prime Factorization of 927 is 3 x 3 x 103

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 685 is 5 x 137

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(654, 927) = 202086

GCD(654, 927) = ( 654 x 927 ) / 202086

GCD(654, 927) = 606258 / 202086

GCD(654, 927) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 847

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

LCM(3, 847) = 2541

GCD(3, 847) = ( 3 x 847 ) / 2541

GCD(3, 847) = 2541 / 2541

GCD(3, 847) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 685

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

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

GCD(1, 685) = 685 / 685

GCD(1, 685) = 1

GCD of 654, 927, 847, 685 is 1
