Therefore, GCD of numbers 117, 471, 388, 284 is 1

Given Input Data is 117, 471, 388, 284

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

Prime Factorization of 117 is 3 x 3 x 13

Prime Factorization of 471 is 3 x 157

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 284 is 2 x 2 x 71

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(117, 471) = 18369

GCD(117, 471) = ( 117 x 471 ) / 18369

GCD(117, 471) = 55107 / 18369

GCD(117, 471) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 388

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

LCM(3, 388) = 1164

GCD(3, 388) = ( 3 x 388 ) / 1164

GCD(3, 388) = 1164 / 1164

GCD(3, 388) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 284

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

LCM(1, 284) = 284

GCD(1, 284) = ( 1 x 284 ) / 284

GCD(1, 284) = 284 / 284

GCD(1, 284) = 1

GCD of 117, 471, 388, 284 is 1
