Given Input Data is 504, 903, 28, 235

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

Prime Factorization of 504 is 2 x 2 x 2 x 3 x 3 x 7

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 235 is 5 x 47

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(504, 903) = 21672

GCD(504, 903) = ( 504 x 903 ) / 21672

GCD(504, 903) = 455112 / 21672

GCD(504, 903) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 28

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

LCM(21, 28) = 84

GCD(21, 28) = ( 21 x 28 ) / 84

GCD(21, 28) = 588 / 84

GCD(21, 28) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 235

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

LCM(7, 235) = 1645

GCD(7, 235) = ( 7 x 235 ) / 1645

GCD(7, 235) = 1645 / 1645

GCD(7, 235) = 1

GCD of 504, 903, 28, 235 is 1
