Therefore, GCD of numbers 880, 806, 721 is 1

Given Input Data is 880, 806, 721

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

Prime Factorization of 880 is 2 x 2 x 2 x 2 x 5 x 11

Prime Factorization of 806 is 2 x 13 x 31

Prime Factorization of 721 is 7 x 103

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(880, 806) = 354640

GCD(880, 806) = ( 880 x 806 ) / 354640

GCD(880, 806) = 709280 / 354640

GCD(880, 806) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 721

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

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

GCD(2, 721) = 1442 / 1442

GCD(2, 721) = 1

GCD of 880, 806, 721 is 1
