Given Input Data is 54, 966, 819, 649

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 966 is 2 x 3 x 7 x 23

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

Prime Factorization of 649 is 11 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(54, 966) = 8694

GCD(54, 966) = ( 54 x 966 ) / 8694

GCD(54, 966) = 52164 / 8694

GCD(54, 966) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 819

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

LCM(6, 819) = 1638

GCD(6, 819) = ( 6 x 819 ) / 1638

GCD(6, 819) = 4914 / 1638

GCD(6, 819) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 649

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

LCM(3, 649) = 1947

GCD(3, 649) = ( 3 x 649 ) / 1947

GCD(3, 649) = 1947 / 1947

GCD(3, 649) = 1

GCD of 54, 966, 819, 649 is 1
