Given Input Data is 649, 572, 847, 637

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

Prime Factorization of 649 is 11 x 59

Prime Factorization of 572 is 2 x 2 x 11 x 13

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 637 is 7 x 7 x 13

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(649, 572) = 33748

GCD(649, 572) = ( 649 x 572 ) / 33748

GCD(649, 572) = 371228 / 33748

GCD(649, 572) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 847

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

LCM(11, 847) = 847

GCD(11, 847) = ( 11 x 847 ) / 847

GCD(11, 847) = 9317 / 847

GCD(11, 847) = 11

Step3:

Here we consider the GCD from the above i.e. 11 as first number and the next as 637

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

LCM(11, 637) = 7007

GCD(11, 637) = ( 11 x 637 ) / 7007

GCD(11, 637) = 7007 / 7007

GCD(11, 637) = 1

GCD of 649, 572, 847, 637 is 1
