Therefore, GCD of numbers 56, 721, 178, 296 is 1

Given Input Data is 56, 721, 178, 296

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

Prime Factorization of 56 is 2 x 2 x 2 x 7

Prime Factorization of 721 is 7 x 103

Prime Factorization of 178 is 2 x 89

Prime Factorization of 296 is 2 x 2 x 2 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(56, 721) = 5768

GCD(56, 721) = ( 56 x 721 ) / 5768

GCD(56, 721) = 40376 / 5768

GCD(56, 721) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 178

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

LCM(7, 178) = 1246

GCD(7, 178) = ( 7 x 178 ) / 1246

GCD(7, 178) = 1246 / 1246

GCD(7, 178) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 296

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

LCM(1, 296) = 296

GCD(1, 296) = ( 1 x 296 ) / 296

GCD(1, 296) = 296 / 296

GCD(1, 296) = 1

GCD of 56, 721, 178, 296 is 1
