Therefore, GCD of numbers 811, 227, 538, 391 is 1

Given Input Data is 811, 227, 538, 391

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

Prime Factorization of 811 is 811

Prime Factorization of 227 is 227

Prime Factorization of 538 is 2 x 269

Prime Factorization of 391 is 17 x 23

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(811, 227) = 184097

GCD(811, 227) = ( 811 x 227 ) / 184097

GCD(811, 227) = 184097 / 184097

GCD(811, 227) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 538

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

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

GCD(1, 538) = 538 / 538

GCD(1, 538) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 391

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

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

GCD(1, 391) = 391 / 391

GCD(1, 391) = 1

GCD of 811, 227, 538, 391 is 1
