Given Input Data is 819, 210, 611, 767

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

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 611 is 13 x 47

Prime Factorization of 767 is 13 x 59

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(819, 210) = 8190

GCD(819, 210) = ( 819 x 210 ) / 8190

GCD(819, 210) = 171990 / 8190

GCD(819, 210) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 611

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

LCM(21, 611) = 12831

GCD(21, 611) = ( 21 x 611 ) / 12831

GCD(21, 611) = 12831 / 12831

GCD(21, 611) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 767

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

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

GCD(1, 767) = 767 / 767

GCD(1, 767) = 1

GCD of 819, 210, 611, 767 is 1
