Given Input Data is 387, 523, 811

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

Prime Factorization of 387 is 3 x 3 x 43

Prime Factorization of 523 is 523

Prime Factorization of 811 is 811

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(387, 523) = 202401

GCD(387, 523) = ( 387 x 523 ) / 202401

GCD(387, 523) = 202401 / 202401

GCD(387, 523) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 387, 523, 811 is 1
