Therefore, GCD of numbers 84, 558, 685, 188 is 1

Given Input Data is 84, 558, 685, 188

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 685 is 5 x 137

Prime Factorization of 188 is 2 x 2 x 47

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(84, 558) = 7812

GCD(84, 558) = ( 84 x 558 ) / 7812

GCD(84, 558) = 46872 / 7812

GCD(84, 558) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 685

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

LCM(6, 685) = 4110

GCD(6, 685) = ( 6 x 685 ) / 4110

GCD(6, 685) = 4110 / 4110

GCD(6, 685) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 188

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

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

GCD(1, 188) = 188 / 188

GCD(1, 188) = 1

GCD of 84, 558, 685, 188 is 1
