Therefore, GCD of numbers 966, 861, 19, 777 is 1

Given Input Data is 966, 861, 19, 777

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

Prime Factorization of 966 is 2 x 3 x 7 x 23

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 19 is 19

Prime Factorization of 777 is 3 x 7 x 37

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(966, 861) = 39606

GCD(966, 861) = ( 966 x 861 ) / 39606

GCD(966, 861) = 831726 / 39606

GCD(966, 861) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 19

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

LCM(21, 19) = 399

GCD(21, 19) = ( 21 x 19 ) / 399

GCD(21, 19) = 399 / 399

GCD(21, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 777

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

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

GCD(1, 777) = 777 / 777

GCD(1, 777) = 1

GCD of 966, 861, 19, 777 is 1
