Therefore, GCD of numbers 811, 809, 483, 261 is 1

Given Input Data is 811, 809, 483, 261

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

Prime Factorization of 811 is 811

Prime Factorization of 809 is 809

Prime Factorization of 483 is 3 x 7 x 23

Prime Factorization of 261 is 3 x 3 x 29

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(811, 809) = 656099

GCD(811, 809) = ( 811 x 809 ) / 656099

GCD(811, 809) = 656099 / 656099

GCD(811, 809) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 483

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

LCM(1, 483) = 483

GCD(1, 483) = ( 1 x 483 ) / 483

GCD(1, 483) = 483 / 483

GCD(1, 483) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 811, 809, 483, 261 is 1
