Therefore, GCD of numbers 781, 849, 439, 429 is 1

Given Input Data is 781, 849, 439, 429

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 849 is 3 x 283

Prime Factorization of 439 is 439

Prime Factorization of 429 is 3 x 11 x 13

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(781, 849) = 663069

GCD(781, 849) = ( 781 x 849 ) / 663069

GCD(781, 849) = 663069 / 663069

GCD(781, 849) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 429

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

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

GCD(1, 429) = 429 / 429

GCD(1, 429) = 1

GCD of 781, 849, 439, 429 is 1
