Therefore, GCD of numbers 402, 729, 39, 301 is 1

Given Input Data is 402, 729, 39, 301

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

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 39 is 3 x 13

Prime Factorization of 301 is 7 x 43

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(402, 729) = 97686

GCD(402, 729) = ( 402 x 729 ) / 97686

GCD(402, 729) = 293058 / 97686

GCD(402, 729) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 39

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

LCM(3, 39) = 39

GCD(3, 39) = ( 3 x 39 ) / 39

GCD(3, 39) = 117 / 39

GCD(3, 39) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 301

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

LCM(3, 301) = 903

GCD(3, 301) = ( 3 x 301 ) / 903

GCD(3, 301) = 903 / 903

GCD(3, 301) = 1

GCD of 402, 729, 39, 301 is 1
