Given Input Data is 357, 629, 421

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

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 629 is 17 x 37

Prime Factorization of 421 is 421

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(357, 629) = 13209

GCD(357, 629) = ( 357 x 629 ) / 13209

GCD(357, 629) = 224553 / 13209

GCD(357, 629) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 421

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

LCM(17, 421) = 7157

GCD(17, 421) = ( 17 x 421 ) / 7157

GCD(17, 421) = 7157 / 7157

GCD(17, 421) = 1

GCD of 357, 629, 421 is 1
