Given Input Data is 221, 468, 651

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

Prime Factorization of 221 is 13 x 17

Prime Factorization of 468 is 2 x 2 x 3 x 3 x 13

Prime Factorization of 651 is 3 x 7 x 31

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(221, 468) = 7956

GCD(221, 468) = ( 221 x 468 ) / 7956

GCD(221, 468) = 103428 / 7956

GCD(221, 468) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 651

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

LCM(13, 651) = 8463

GCD(13, 651) = ( 13 x 651 ) / 8463

GCD(13, 651) = 8463 / 8463

GCD(13, 651) = 1

GCD of 221, 468, 651 is 1
