Given Input Data is 763, 259, 143, 605

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

Prime Factorization of 763 is 7 x 109

Prime Factorization of 259 is 7 x 37

Prime Factorization of 143 is 11 x 13

Prime Factorization of 605 is 5 x 11 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(763, 259) = 28231

GCD(763, 259) = ( 763 x 259 ) / 28231

GCD(763, 259) = 197617 / 28231

GCD(763, 259) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 143

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

LCM(7, 143) = 1001

GCD(7, 143) = ( 7 x 143 ) / 1001

GCD(7, 143) = 1001 / 1001

GCD(7, 143) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 763, 259, 143, 605 is 1
