Given Input Data is 882, 455, 27, 657

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

Prime Factorization of 882 is 2 x 3 x 3 x 7 x 7

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 657 is 3 x 3 x 73

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(882, 455) = 57330

GCD(882, 455) = ( 882 x 455 ) / 57330

GCD(882, 455) = 401310 / 57330

GCD(882, 455) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 27

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

LCM(7, 27) = 189

GCD(7, 27) = ( 7 x 27 ) / 189

GCD(7, 27) = 189 / 189

GCD(7, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 657

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

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

GCD(1, 657) = 657 / 657

GCD(1, 657) = 1

GCD of 882, 455, 27, 657 is 1
