Therefore, GCD of numbers 571, 438, 657, 211 is 1

Given Input Data is 571, 438, 657, 211

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

Prime Factorization of 571 is 571

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 657 is 3 x 3 x 73

Prime Factorization of 211 is 211

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, 438) = 250098

GCD(571, 438) = ( 571 x 438 ) / 250098

GCD(571, 438) = 250098 / 250098

GCD(571, 438) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 211

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

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

GCD(1, 211) = 211 / 211

GCD(1, 211) = 1

GCD of 571, 438, 657, 211 is 1
