We found the divisors of 721, 764, 845, 706 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 721, 764, 845, 706 is 1.

Therefore, GCD of numbers 721, 764, 845, 706 is 1

Given Input Data is 721, 764, 845, 706

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 764 is 2 x 2 x 191

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 706 is 2 x 353

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, 764) = 550844

GCD(721, 764) = ( 721 x 764 ) / 550844

GCD(721, 764) = 550844 / 550844

GCD(721, 764) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 845

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

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

GCD(1, 845) = 845 / 845

GCD(1, 845) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 706

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

LCM(1, 706) = 706

GCD(1, 706) = ( 1 x 706 ) / 706

GCD(1, 706) = 706 / 706

GCD(1, 706) = 1

GCD of 721, 764, 845, 706 is 1
