Given Input Data is 620, 725, 504, 386

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

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 725 is 5 x 5 x 29

Prime Factorization of 504 is 2 x 2 x 2 x 3 x 3 x 7

Prime Factorization of 386 is 2 x 193

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(620, 725) = 89900

GCD(620, 725) = ( 620 x 725 ) / 89900

GCD(620, 725) = 449500 / 89900

GCD(620, 725) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 504

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

LCM(5, 504) = 2520

GCD(5, 504) = ( 5 x 504 ) / 2520

GCD(5, 504) = 2520 / 2520

GCD(5, 504) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 386

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

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

GCD(1, 386) = 386 / 386

GCD(1, 386) = 1

GCD of 620, 725, 504, 386 is 1
