Given Input Data is 939, 394, 85, 549

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

Prime Factorization of 939 is 3 x 313

Prime Factorization of 394 is 2 x 197

Prime Factorization of 85 is 5 x 17

Prime Factorization of 549 is 3 x 3 x 61

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, 394) = 369966

GCD(939, 394) = ( 939 x 394 ) / 369966

GCD(939, 394) = 369966 / 369966

GCD(939, 394) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 549

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

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

GCD(1, 549) = 549 / 549

GCD(1, 549) = 1

GCD of 939, 394, 85, 549 is 1
