Given Input Data is 520, 700, 643, 626

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

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7

Prime Factorization of 643 is 643

Prime Factorization of 626 is 2 x 313

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(520, 700) = 18200

GCD(520, 700) = ( 520 x 700 ) / 18200

GCD(520, 700) = 364000 / 18200

GCD(520, 700) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 643

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

LCM(20, 643) = 12860

GCD(20, 643) = ( 20 x 643 ) / 12860

GCD(20, 643) = 12860 / 12860

GCD(20, 643) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 626

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

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

GCD(1, 626) = 626 / 626

GCD(1, 626) = 1

GCD of 520, 700, 643, 626 is 1
