Given Input Data is 858, 453, 545, 317

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

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 453 is 3 x 151

Prime Factorization of 545 is 5 x 109

Prime Factorization of 317 is 317

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(858, 453) = 129558

GCD(858, 453) = ( 858 x 453 ) / 129558

GCD(858, 453) = 388674 / 129558

GCD(858, 453) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 545

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

LCM(3, 545) = 1635

GCD(3, 545) = ( 3 x 545 ) / 1635

GCD(3, 545) = 1635 / 1635

GCD(3, 545) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 317

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

LCM(1, 317) = 317

GCD(1, 317) = ( 1 x 317 ) / 317

GCD(1, 317) = 317 / 317

GCD(1, 317) = 1

GCD of 858, 453, 545, 317 is 1
