Given Input Data is 426, 243, 845, 537

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

Prime Factorization of 426 is 2 x 3 x 71

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 537 is 3 x 179

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(426, 243) = 34506

GCD(426, 243) = ( 426 x 243 ) / 34506

GCD(426, 243) = 103518 / 34506

GCD(426, 243) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 845

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

LCM(3, 845) = 2535

GCD(3, 845) = ( 3 x 845 ) / 2535

GCD(3, 845) = 2535 / 2535

GCD(3, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 537

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

LCM(1, 537) = 537

GCD(1, 537) = ( 1 x 537 ) / 537

GCD(1, 537) = 537 / 537

GCD(1, 537) = 1

GCD of 426, 243, 845, 537 is 1
