Given Input Data is 261, 243, 843, 541

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

Prime Factorization of 261 is 3 x 3 x 29

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 541 is 541

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(261, 243) = 7047

GCD(261, 243) = ( 261 x 243 ) / 7047

GCD(261, 243) = 63423 / 7047

GCD(261, 243) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 843

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

LCM(9, 843) = 2529

GCD(9, 843) = ( 9 x 843 ) / 2529

GCD(9, 843) = 7587 / 2529

GCD(9, 843) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 541

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

LCM(3, 541) = 1623

GCD(3, 541) = ( 3 x 541 ) / 1623

GCD(3, 541) = 1623 / 1623

GCD(3, 541) = 1

GCD of 261, 243, 843, 541 is 1
