Therefore, GCD of numbers 843, 870, 835, 671 is 1

Given Input Data is 843, 870, 835, 671

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 835 is 5 x 167

Prime Factorization of 671 is 11 x 61

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(843, 870) = 244470

GCD(843, 870) = ( 843 x 870 ) / 244470

GCD(843, 870) = 733410 / 244470

GCD(843, 870) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 835

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

LCM(3, 835) = 2505

GCD(3, 835) = ( 3 x 835 ) / 2505

GCD(3, 835) = 2505 / 2505

GCD(3, 835) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 671

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

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

GCD(1, 671) = 671 / 671

GCD(1, 671) = 1

GCD of 843, 870, 835, 671 is 1
