Given Input Data is 797, 219, 54, 561

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

Prime Factorization of 797 is 797

Prime Factorization of 219 is 3 x 73

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 561 is 3 x 11 x 17

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(797, 219) = 174543

GCD(797, 219) = ( 797 x 219 ) / 174543

GCD(797, 219) = 174543 / 174543

GCD(797, 219) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 54

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

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

GCD(1, 54) = 54 / 54

GCD(1, 54) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 561

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

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

GCD(1, 561) = 561 / 561

GCD(1, 561) = 1

GCD of 797, 219, 54, 561 is 1
