Therefore, GCD of numbers 577, 208, 721 is 1

Given Input Data is 577, 208, 721

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

Prime Factorization of 577 is 577

Prime Factorization of 208 is 2 x 2 x 2 x 2 x 13

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(577, 208) = 120016

GCD(577, 208) = ( 577 x 208 ) / 120016

GCD(577, 208) = 120016 / 120016

GCD(577, 208) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 721

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

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

GCD(1, 721) = 721 / 721

GCD(1, 721) = 1

GCD of 577, 208, 721 is 1
