Therefore, GCD of numbers 28, 189, 501, 472 is 1

Given Input Data is 28, 189, 501, 472

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 189 is 3 x 3 x 3 x 7

Prime Factorization of 501 is 3 x 167

Prime Factorization of 472 is 2 x 2 x 2 x 59

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, 189) = 756

GCD(28, 189) = ( 28 x 189 ) / 756

GCD(28, 189) = 5292 / 756

GCD(28, 189) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 501

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

LCM(7, 501) = 3507

GCD(7, 501) = ( 7 x 501 ) / 3507

GCD(7, 501) = 3507 / 3507

GCD(7, 501) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 472

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

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

GCD(1, 472) = 472 / 472

GCD(1, 472) = 1

GCD of 28, 189, 501, 472 is 1
