Given Input Data is 618, 434, 524, 261

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 524 is 2 x 2 x 131

Prime Factorization of 261 is 3 x 3 x 29

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(618, 434) = 134106

GCD(618, 434) = ( 618 x 434 ) / 134106

GCD(618, 434) = 268212 / 134106

GCD(618, 434) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 524

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

LCM(2, 524) = 524

GCD(2, 524) = ( 2 x 524 ) / 524

GCD(2, 524) = 1048 / 524

GCD(2, 524) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 261

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

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

GCD(2, 261) = 522 / 522

GCD(2, 261) = 1

GCD of 618, 434, 524, 261 is 1
