Given Input Data is 28, 450, 294, 641

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 294 is 2 x 3 x 7 x 7

Prime Factorization of 641 is 641

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(28, 450) = 6300

GCD(28, 450) = ( 28 x 450 ) / 6300

GCD(28, 450) = 12600 / 6300

GCD(28, 450) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 294

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

LCM(2, 294) = 294

GCD(2, 294) = ( 2 x 294 ) / 294

GCD(2, 294) = 588 / 294

GCD(2, 294) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 641

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

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

GCD(2, 641) = 1282 / 1282

GCD(2, 641) = 1

GCD of 28, 450, 294, 641 is 1
