Given Input Data is 669, 630, 422

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

Prime Factorization of 669 is 3 x 223

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

Prime Factorization of 422 is 2 x 211

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(669, 630) = 140490

GCD(669, 630) = ( 669 x 630 ) / 140490

GCD(669, 630) = 421470 / 140490

GCD(669, 630) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 422

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

LCM(3, 422) = 1266

GCD(3, 422) = ( 3 x 422 ) / 1266

GCD(3, 422) = 1266 / 1266

GCD(3, 422) = 1

GCD of 669, 630, 422 is 1
