Therefore, GCD of numbers 196, 861, 807, 389 is 1

Given Input Data is 196, 861, 807, 389

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

Prime Factorization of 196 is 2 x 2 x 7 x 7

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 807 is 3 x 269

Prime Factorization of 389 is 389

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(196, 861) = 24108

GCD(196, 861) = ( 196 x 861 ) / 24108

GCD(196, 861) = 168756 / 24108

GCD(196, 861) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 807

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

LCM(7, 807) = 5649

GCD(7, 807) = ( 7 x 807 ) / 5649

GCD(7, 807) = 5649 / 5649

GCD(7, 807) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 389

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

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

GCD(1, 389) = 389 / 389

GCD(1, 389) = 1

GCD of 196, 861, 807, 389 is 1
