Therefore, GCD of numbers 210, 328, 647 is 1

Given Input Data is 210, 328, 647

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 328 is 2 x 2 x 2 x 41

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(210, 328) = 34440

GCD(210, 328) = ( 210 x 328 ) / 34440

GCD(210, 328) = 68880 / 34440

GCD(210, 328) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 647

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

LCM(2, 647) = 1294

GCD(2, 647) = ( 2 x 647 ) / 1294

GCD(2, 647) = 1294 / 1294

GCD(2, 647) = 1

GCD of 210, 328, 647 is 1
