Therefore, GCD of numbers 455, 949, 471, 136 is 1

Given Input Data is 455, 949, 471, 136

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 471 is 3 x 157

Prime Factorization of 136 is 2 x 2 x 2 x 17

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 471

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

LCM(13, 471) = 6123

GCD(13, 471) = ( 13 x 471 ) / 6123

GCD(13, 471) = 6123 / 6123

GCD(13, 471) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 136

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

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

GCD(1, 136) = 136 / 136

GCD(1, 136) = 1

GCD of 455, 949, 471, 136 is 1
