Given Input Data is 511, 971, 381, 809

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 971 is 971

Prime Factorization of 381 is 3 x 127

Prime Factorization of 809 is 809

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(511, 971) = 496181

GCD(511, 971) = ( 511 x 971 ) / 496181

GCD(511, 971) = 496181 / 496181

GCD(511, 971) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 381

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

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

GCD(1, 381) = 381 / 381

GCD(1, 381) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 809

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

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

GCD(1, 809) = 809 / 809

GCD(1, 809) = 1

GCD of 511, 971, 381, 809 is 1
