Therefore, GCD of numbers 931, 861, 777, 859 is 1

Given Input Data is 931, 861, 777, 859

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

Prime Factorization of 931 is 7 x 7 x 19

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 859 is 859

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(931, 861) = 114513

GCD(931, 861) = ( 931 x 861 ) / 114513

GCD(931, 861) = 801591 / 114513

GCD(931, 861) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 777

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

LCM(7, 777) = 777

GCD(7, 777) = ( 7 x 777 ) / 777

GCD(7, 777) = 5439 / 777

GCD(7, 777) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 859

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

LCM(7, 859) = 6013

GCD(7, 859) = ( 7 x 859 ) / 6013

GCD(7, 859) = 6013 / 6013

GCD(7, 859) = 1

GCD of 931, 861, 777, 859 is 1
