Therefore, GCD of numbers 721, 866, 777 is 1

Given Input Data is 721, 866, 777

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 866 is 2 x 433

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(721, 866) = 624386

GCD(721, 866) = ( 721 x 866 ) / 624386

GCD(721, 866) = 624386 / 624386

GCD(721, 866) = 1

Step2:

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 721, 866, 777 is 1
