Given Input Data is 810, 819, 688, 641

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

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

Prime Factorization of 641 is 641

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(810, 819) = 73710

GCD(810, 819) = ( 810 x 819 ) / 73710

GCD(810, 819) = 663390 / 73710

GCD(810, 819) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 688

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

LCM(9, 688) = 6192

GCD(9, 688) = ( 9 x 688 ) / 6192

GCD(9, 688) = 6192 / 6192

GCD(9, 688) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 810, 819, 688, 641 is 1
