Given Input Data is 646, 304, 763

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

Prime Factorization of 763 is 7 x 109

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(646, 304) = 5168

GCD(646, 304) = ( 646 x 304 ) / 5168

GCD(646, 304) = 196384 / 5168

GCD(646, 304) = 38

Step2:

Here we consider the GCD from the above i.e. 38 as first number and the next as 763

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

LCM(38, 763) = 28994

GCD(38, 763) = ( 38 x 763 ) / 28994

GCD(38, 763) = 28994 / 28994

GCD(38, 763) = 1

GCD of 646, 304, 763 is 1
