Given Input Data is 571, 899, 979, 561

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

Prime Factorization of 571 is 571

Prime Factorization of 899 is 29 x 31

Prime Factorization of 979 is 11 x 89

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(571, 899) = 513329

GCD(571, 899) = ( 571 x 899 ) / 513329

GCD(571, 899) = 513329 / 513329

GCD(571, 899) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 979

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

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

GCD(1, 979) = 979 / 979

GCD(1, 979) = 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 571, 899, 979, 561 is 1
