Given Input Data is 485, 880, 27, 817

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

Prime Factorization of 485 is 5 x 97

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 817 is 19 x 43

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(485, 880) = 85360

GCD(485, 880) = ( 485 x 880 ) / 85360

GCD(485, 880) = 426800 / 85360

GCD(485, 880) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 27

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

LCM(5, 27) = 135

GCD(5, 27) = ( 5 x 27 ) / 135

GCD(5, 27) = 135 / 135

GCD(5, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 817

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

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

GCD(1, 817) = 817 / 817

GCD(1, 817) = 1

GCD of 485, 880, 27, 817 is 1
