Given Input Data is 609, 252, 781, 311

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

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 252 is 2 x 2 x 3 x 3 x 7

Prime Factorization of 781 is 11 x 71

Prime Factorization of 311 is 311

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(609, 252) = 7308

GCD(609, 252) = ( 609 x 252 ) / 7308

GCD(609, 252) = 153468 / 7308

GCD(609, 252) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 781

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

LCM(21, 781) = 16401

GCD(21, 781) = ( 21 x 781 ) / 16401

GCD(21, 781) = 16401 / 16401

GCD(21, 781) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 311

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

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

GCD(1, 311) = 311 / 311

GCD(1, 311) = 1

GCD of 609, 252, 781, 311 is 1
