Therefore, GCD of numbers 207, 129, 591, 220 is 1

Given Input Data is 207, 129, 591, 220

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 129 is 3 x 43

Prime Factorization of 591 is 3 x 197

Prime Factorization of 220 is 2 x 2 x 5 x 11

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(207, 129) = 8901

GCD(207, 129) = ( 207 x 129 ) / 8901

GCD(207, 129) = 26703 / 8901

GCD(207, 129) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 591

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

LCM(3, 591) = 591

GCD(3, 591) = ( 3 x 591 ) / 591

GCD(3, 591) = 1773 / 591

GCD(3, 591) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 220

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

LCM(3, 220) = 660

GCD(3, 220) = ( 3 x 220 ) / 660

GCD(3, 220) = 660 / 660

GCD(3, 220) = 1

GCD of 207, 129, 591, 220 is 1
