Therefore, GCD of numbers 939, 831, 215, 609 is 1

Given Input Data is 939, 831, 215, 609

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

Prime Factorization of 939 is 3 x 313

Prime Factorization of 831 is 3 x 277

Prime Factorization of 215 is 5 x 43

Prime Factorization of 609 is 3 x 7 x 29

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(939, 831) = 260103

GCD(939, 831) = ( 939 x 831 ) / 260103

GCD(939, 831) = 780309 / 260103

GCD(939, 831) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 215

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

LCM(3, 215) = 645

GCD(3, 215) = ( 3 x 215 ) / 645

GCD(3, 215) = 645 / 645

GCD(3, 215) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 609

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

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

GCD(1, 609) = 609 / 609

GCD(1, 609) = 1

GCD of 939, 831, 215, 609 is 1
