Therefore, GCD of numbers 429, 671, 454, 128 is 1

Given Input Data is 429, 671, 454, 128

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

Prime Factorization of 429 is 3 x 11 x 13

Prime Factorization of 671 is 11 x 61

Prime Factorization of 454 is 2 x 227

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

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(429, 671) = 26169

GCD(429, 671) = ( 429 x 671 ) / 26169

GCD(429, 671) = 287859 / 26169

GCD(429, 671) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 454

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

LCM(11, 454) = 4994

GCD(11, 454) = ( 11 x 454 ) / 4994

GCD(11, 454) = 4994 / 4994

GCD(11, 454) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 128

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

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

GCD(1, 128) = 128 / 128

GCD(1, 128) = 1

GCD of 429, 671, 454, 128 is 1
