Given Input Data is 164, 836, 647

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

Prime Factorization of 164 is 2 x 2 x 41

Prime Factorization of 836 is 2 x 2 x 11 x 19

Prime Factorization of 647 is 647

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(164, 836) = 34276

GCD(164, 836) = ( 164 x 836 ) / 34276

GCD(164, 836) = 137104 / 34276

GCD(164, 836) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 647

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

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

GCD(4, 647) = 2588 / 2588

GCD(4, 647) = 1

GCD of 164, 836, 647 is 1
