Given Input Data is 905, 490, 99, 485

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

Prime Factorization of 905 is 5 x 181

Prime Factorization of 490 is 2 x 5 x 7 x 7

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 485 is 5 x 97

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(905, 490) = 88690

GCD(905, 490) = ( 905 x 490 ) / 88690

GCD(905, 490) = 443450 / 88690

GCD(905, 490) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 99

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

LCM(5, 99) = 495

GCD(5, 99) = ( 5 x 99 ) / 495

GCD(5, 99) = 495 / 495

GCD(5, 99) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 485

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

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

GCD(1, 485) = 485 / 485

GCD(1, 485) = 1

GCD of 905, 490, 99, 485 is 1
