Given Input Data is 680, 385, 622, 397

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

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 622 is 2 x 311

Prime Factorization of 397 is 397

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(680, 385) = 52360

GCD(680, 385) = ( 680 x 385 ) / 52360

GCD(680, 385) = 261800 / 52360

GCD(680, 385) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 622

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

LCM(5, 622) = 3110

GCD(5, 622) = ( 5 x 622 ) / 3110

GCD(5, 622) = 3110 / 3110

GCD(5, 622) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 397

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

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

GCD(1, 397) = 397 / 397

GCD(1, 397) = 1

GCD of 680, 385, 622, 397 is 1
