Given Input Data is 663, 150, 189, 673

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 150 is 2 x 3 x 5 x 5

Prime Factorization of 189 is 3 x 3 x 3 x 7

Prime Factorization of 673 is 673

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(663, 150) = 33150

GCD(663, 150) = ( 663 x 150 ) / 33150

GCD(663, 150) = 99450 / 33150

GCD(663, 150) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 189

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

LCM(3, 189) = 189

GCD(3, 189) = ( 3 x 189 ) / 189

GCD(3, 189) = 567 / 189

GCD(3, 189) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 673

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

LCM(3, 673) = 2019

GCD(3, 673) = ( 3 x 673 ) / 2019

GCD(3, 673) = 2019 / 2019

GCD(3, 673) = 1

GCD of 663, 150, 189, 673 is 1
