Given Input Data is 843, 810, 249, 253

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 249 is 3 x 83

Prime Factorization of 253 is 11 x 23

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(843, 810) = 227610

GCD(843, 810) = ( 843 x 810 ) / 227610

GCD(843, 810) = 682830 / 227610

GCD(843, 810) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 249

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

LCM(3, 249) = 249

GCD(3, 249) = ( 3 x 249 ) / 249

GCD(3, 249) = 747 / 249

GCD(3, 249) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 253

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

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

GCD(3, 253) = 759 / 759

GCD(3, 253) = 1

GCD of 843, 810, 249, 253 is 1
