Given Input Data is 392, 144, 939, 245

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

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 939 is 3 x 313

Prime Factorization of 245 is 5 x 7 x 7

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(392, 144) = 7056

GCD(392, 144) = ( 392 x 144 ) / 7056

GCD(392, 144) = 56448 / 7056

GCD(392, 144) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 939

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

LCM(8, 939) = 7512

GCD(8, 939) = ( 8 x 939 ) / 7512

GCD(8, 939) = 7512 / 7512

GCD(8, 939) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 392, 144, 939, 245 is 1
