Given Input Data is 72, 561, 439, 229

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

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 439 is 439

Prime Factorization of 229 is 229

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(72, 561) = 13464

GCD(72, 561) = ( 72 x 561 ) / 13464

GCD(72, 561) = 40392 / 13464

GCD(72, 561) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 439

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

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

GCD(3, 439) = 1317 / 1317

GCD(3, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 229

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

LCM(1, 229) = 229

GCD(1, 229) = ( 1 x 229 ) / 229

GCD(1, 229) = 229 / 229

GCD(1, 229) = 1

GCD of 72, 561, 439, 229 is 1
