Therefore, GCD of numbers 197, 604, 646 is 1

Given Input Data is 197, 604, 646

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

Prime Factorization of 197 is 197

Prime Factorization of 604 is 2 x 2 x 151

Prime Factorization of 646 is 2 x 17 x 19

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(197, 604) = 118988

GCD(197, 604) = ( 197 x 604 ) / 118988

GCD(197, 604) = 118988 / 118988

GCD(197, 604) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 646

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

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

GCD(1, 646) = 646 / 646

GCD(1, 646) = 1

GCD of 197, 604, 646 is 1
