Therefore, GCD of numbers 607, 817, 73, 391 is 1

Given Input Data is 607, 817, 73, 391

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

Prime Factorization of 607 is 607

Prime Factorization of 817 is 19 x 43

Prime Factorization of 73 is 73

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(607, 817) = 495919

GCD(607, 817) = ( 607 x 817 ) / 495919

GCD(607, 817) = 495919 / 495919

GCD(607, 817) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 73

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

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

GCD(1, 73) = 73 / 73

GCD(1, 73) = 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 607, 817, 73, 391 is 1
