Given Input Data is 681, 648, 99, 959

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 959 is 7 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(681, 648) = 147096

GCD(681, 648) = ( 681 x 648 ) / 147096

GCD(681, 648) = 441288 / 147096

GCD(681, 648) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 99

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

LCM(3, 99) = 99

GCD(3, 99) = ( 3 x 99 ) / 99

GCD(3, 99) = 297 / 99

GCD(3, 99) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 959

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

LCM(3, 959) = 2877

GCD(3, 959) = ( 3 x 959 ) / 2877

GCD(3, 959) = 2877 / 2877

GCD(3, 959) = 1

GCD of 681, 648, 99, 959 is 1
