Given Input Data is 513, 396, 634, 220

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

Prime Factorization of 513 is 3 x 3 x 3 x 19

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

Prime Factorization of 634 is 2 x 317

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(513, 396) = 22572

GCD(513, 396) = ( 513 x 396 ) / 22572

GCD(513, 396) = 203148 / 22572

GCD(513, 396) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 634

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

LCM(9, 634) = 5706

GCD(9, 634) = ( 9 x 634 ) / 5706

GCD(9, 634) = 5706 / 5706

GCD(9, 634) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 220

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

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

GCD(1, 220) = 220 / 220

GCD(1, 220) = 1

GCD of 513, 396, 634, 220 is 1
