Therefore, GCD of numbers 820, 630, 471 is 1

Given Input Data is 820, 630, 471

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

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 471 is 3 x 157

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(820, 630) = 51660

GCD(820, 630) = ( 820 x 630 ) / 51660

GCD(820, 630) = 516600 / 51660

GCD(820, 630) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 471

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

LCM(10, 471) = 4710

GCD(10, 471) = ( 10 x 471 ) / 4710

GCD(10, 471) = 4710 / 4710

GCD(10, 471) = 1

GCD of 820, 630, 471 is 1
