Given Input Data is 820, 352, 473

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 352 is 2 x 2 x 2 x 2 x 2 x 11

Prime Factorization of 473 is 11 x 43

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, 352) = 72160

GCD(820, 352) = ( 820 x 352 ) / 72160

GCD(820, 352) = 288640 / 72160

GCD(820, 352) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 473

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

LCM(4, 473) = 1892

GCD(4, 473) = ( 4 x 473 ) / 1892

GCD(4, 473) = 1892 / 1892

GCD(4, 473) = 1

GCD of 820, 352, 473 is 1
