Given Input Data is 627, 861, 273, 731

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

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 273 is 3 x 7 x 13

Prime Factorization of 731 is 17 x 43

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(627, 861) = 179949

GCD(627, 861) = ( 627 x 861 ) / 179949

GCD(627, 861) = 539847 / 179949

GCD(627, 861) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 273

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

LCM(3, 273) = 273

GCD(3, 273) = ( 3 x 273 ) / 273

GCD(3, 273) = 819 / 273

GCD(3, 273) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 731

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

LCM(3, 731) = 2193

GCD(3, 731) = ( 3 x 731 ) / 2193

GCD(3, 731) = 2193 / 2193

GCD(3, 731) = 1

GCD of 627, 861, 273, 731 is 1
