Given Input Data is 513, 645, 306, 626

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

Prime Factorization of 513 is 3 x 3 x 3 x 19

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 306 is 2 x 3 x 3 x 17

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(513, 645) = 110295

GCD(513, 645) = ( 513 x 645 ) / 110295

GCD(513, 645) = 330885 / 110295

GCD(513, 645) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 306

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

LCM(3, 306) = 306

GCD(3, 306) = ( 3 x 306 ) / 306

GCD(3, 306) = 918 / 306

GCD(3, 306) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 626

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

LCM(3, 626) = 1878

GCD(3, 626) = ( 3 x 626 ) / 1878

GCD(3, 626) = 1878 / 1878

GCD(3, 626) = 1

GCD of 513, 645, 306, 626 is 1
