Given Input Data is 620, 300, 393, 789

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 300 is 2 x 2 x 3 x 5 x 5

Prime Factorization of 393 is 3 x 131

Prime Factorization of 789 is 3 x 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(620, 300) = 9300

GCD(620, 300) = ( 620 x 300 ) / 9300

GCD(620, 300) = 186000 / 9300

GCD(620, 300) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 393

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

LCM(20, 393) = 7860

GCD(20, 393) = ( 20 x 393 ) / 7860

GCD(20, 393) = 7860 / 7860

GCD(20, 393) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 789

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

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

GCD(1, 789) = 789 / 789

GCD(1, 789) = 1

GCD of 620, 300, 393, 789 is 1
