Given Input Data is 147, 343, 71, 189

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

Prime Factorization of 147 is 3 x 7 x 7

Prime Factorization of 343 is 7 x 7 x 7

Prime Factorization of 71 is 71

Prime Factorization of 189 is 3 x 3 x 3 x 7

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(147, 343) = 1029

GCD(147, 343) = ( 147 x 343 ) / 1029

GCD(147, 343) = 50421 / 1029

GCD(147, 343) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 71

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

LCM(49, 71) = 3479

GCD(49, 71) = ( 49 x 71 ) / 3479

GCD(49, 71) = 3479 / 3479

GCD(49, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 189

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

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

GCD(1, 189) = 189 / 189

GCD(1, 189) = 1

GCD of 147, 343, 71, 189 is 1
