Given Input Data is 647, 795, 21, 593

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

Prime Factorization of 647 is 647

Prime Factorization of 795 is 3 x 5 x 53

Prime Factorization of 21 is 3 x 7

Prime Factorization of 593 is 593

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(647, 795) = 514365

GCD(647, 795) = ( 647 x 795 ) / 514365

GCD(647, 795) = 514365 / 514365

GCD(647, 795) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 593

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

LCM(1, 593) = 593

GCD(1, 593) = ( 1 x 593 ) / 593

GCD(1, 593) = 593 / 593

GCD(1, 593) = 1

GCD of 647, 795, 21, 593 is 1
