Given Input Data is 404, 612, 685, 263

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

Prime Factorization of 404 is 2 x 2 x 101

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

Prime Factorization of 685 is 5 x 137

Prime Factorization of 263 is 263

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(404, 612) = 61812

GCD(404, 612) = ( 404 x 612 ) / 61812

GCD(404, 612) = 247248 / 61812

GCD(404, 612) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 685

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

LCM(4, 685) = 2740

GCD(4, 685) = ( 4 x 685 ) / 2740

GCD(4, 685) = 2740 / 2740

GCD(4, 685) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 263

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

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

GCD(1, 263) = 263 / 263

GCD(1, 263) = 1

GCD of 404, 612, 685, 263 is 1
