Given Input Data is 143, 260, 635, 618

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

Prime Factorization of 143 is 11 x 13

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 635 is 5 x 127

Prime Factorization of 618 is 2 x 3 x 103

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(143, 260) = 2860

GCD(143, 260) = ( 143 x 260 ) / 2860

GCD(143, 260) = 37180 / 2860

GCD(143, 260) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 635

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

LCM(13, 635) = 8255

GCD(13, 635) = ( 13 x 635 ) / 8255

GCD(13, 635) = 8255 / 8255

GCD(13, 635) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 618

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

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

GCD(1, 618) = 618 / 618

GCD(1, 618) = 1

GCD of 143, 260, 635, 618 is 1
