Given Input Data is 126, 798, 79, 243

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

Prime Factorization of 126 is 2 x 3 x 3 x 7

Prime Factorization of 798 is 2 x 3 x 7 x 19

Prime Factorization of 79 is 79

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

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(126, 798) = 2394

GCD(126, 798) = ( 126 x 798 ) / 2394

GCD(126, 798) = 100548 / 2394

GCD(126, 798) = 42

Step2:

Here we consider the GCD from the above i.e. 42 as first number and the next as 79

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

LCM(42, 79) = 3318

GCD(42, 79) = ( 42 x 79 ) / 3318

GCD(42, 79) = 3318 / 3318

GCD(42, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 243

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

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

GCD(1, 243) = 243 / 243

GCD(1, 243) = 1

GCD of 126, 798, 79, 243 is 1
