Therefore, GCD of numbers 78, 344, 939, 603 is 1

Given Input Data is 78, 344, 939, 603

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 344 is 2 x 2 x 2 x 43

Prime Factorization of 939 is 3 x 313

Prime Factorization of 603 is 3 x 3 x 67

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(78, 344) = 13416

GCD(78, 344) = ( 78 x 344 ) / 13416

GCD(78, 344) = 26832 / 13416

GCD(78, 344) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 939

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

LCM(2, 939) = 1878

GCD(2, 939) = ( 2 x 939 ) / 1878

GCD(2, 939) = 1878 / 1878

GCD(2, 939) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 603

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

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

GCD(1, 603) = 603 / 603

GCD(1, 603) = 1

GCD of 78, 344, 939, 603 is 1
