Given Input Data is 406, 868, 511, 806

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

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 868 is 2 x 2 x 7 x 31

Prime Factorization of 511 is 7 x 73

Prime Factorization of 806 is 2 x 13 x 31

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(406, 868) = 25172

GCD(406, 868) = ( 406 x 868 ) / 25172

GCD(406, 868) = 352408 / 25172

GCD(406, 868) = 14

Step2:

Here we consider the GCD from the above i.e. 14 as first number and the next as 511

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

LCM(14, 511) = 1022

GCD(14, 511) = ( 14 x 511 ) / 1022

GCD(14, 511) = 7154 / 1022

GCD(14, 511) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 806

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

LCM(7, 806) = 5642

GCD(7, 806) = ( 7 x 806 ) / 5642

GCD(7, 806) = 5642 / 5642

GCD(7, 806) = 1

GCD of 406, 868, 511, 806 is 1
