Given Input Data is 685, 485, 805, 476

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

Prime Factorization of 685 is 5 x 137

Prime Factorization of 485 is 5 x 97

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 476 is 2 x 2 x 7 x 17

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(685, 485) = 66445

GCD(685, 485) = ( 685 x 485 ) / 66445

GCD(685, 485) = 332225 / 66445

GCD(685, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 805

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

LCM(5, 805) = 805

GCD(5, 805) = ( 5 x 805 ) / 805

GCD(5, 805) = 4025 / 805

GCD(5, 805) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 476

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

LCM(5, 476) = 2380

GCD(5, 476) = ( 5 x 476 ) / 2380

GCD(5, 476) = 2380 / 2380

GCD(5, 476) = 1

GCD of 685, 485, 805, 476 is 1
