Therefore, GCD of numbers 286, 671, 56, 431 is 1

Given Input Data is 286, 671, 56, 431

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

Prime Factorization of 286 is 2 x 11 x 13

Prime Factorization of 671 is 11 x 61

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 431 is 431

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(286, 671) = 17446

GCD(286, 671) = ( 286 x 671 ) / 17446

GCD(286, 671) = 191906 / 17446

GCD(286, 671) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 56

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

LCM(11, 56) = 616

GCD(11, 56) = ( 11 x 56 ) / 616

GCD(11, 56) = 616 / 616

GCD(11, 56) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 431

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

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

GCD(1, 431) = 431 / 431

GCD(1, 431) = 1

GCD of 286, 671, 56, 431 is 1
