Given Input Data is 660, 684, 99, 911

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

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 684 is 2 x 2 x 3 x 3 x 19

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 911 is 911

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(660, 684) = 37620

GCD(660, 684) = ( 660 x 684 ) / 37620

GCD(660, 684) = 451440 / 37620

GCD(660, 684) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 99

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

LCM(12, 99) = 396

GCD(12, 99) = ( 12 x 99 ) / 396

GCD(12, 99) = 1188 / 396

GCD(12, 99) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 911

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

LCM(3, 911) = 2733

GCD(3, 911) = ( 3 x 911 ) / 2733

GCD(3, 911) = 2733 / 2733

GCD(3, 911) = 1

GCD of 660, 684, 99, 911 is 1
