Given Input Data is 455, 949, 193, 294

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 949 is 13 x 73

Prime Factorization of 193 is 193

Prime Factorization of 294 is 2 x 3 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(455, 949) = 33215

GCD(455, 949) = ( 455 x 949 ) / 33215

GCD(455, 949) = 431795 / 33215

GCD(455, 949) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 193

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

LCM(13, 193) = 2509

GCD(13, 193) = ( 13 x 193 ) / 2509

GCD(13, 193) = 2509 / 2509

GCD(13, 193) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 294

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

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

GCD(1, 294) = 294 / 294

GCD(1, 294) = 1

GCD of 455, 949, 193, 294 is 1
