Given Input Data is 721, 679, 459, 481

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

Prime Factorization of 721 is 7 x 103

Prime Factorization of 679 is 7 x 97

Prime Factorization of 459 is 3 x 3 x 3 x 17

Prime Factorization of 481 is 13 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, 679) = 69937

GCD(721, 679) = ( 721 x 679 ) / 69937

GCD(721, 679) = 489559 / 69937

GCD(721, 679) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 459

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

LCM(7, 459) = 3213

GCD(7, 459) = ( 7 x 459 ) / 3213

GCD(7, 459) = 3213 / 3213

GCD(7, 459) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 481

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

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

GCD(1, 481) = 481 / 481

GCD(1, 481) = 1

GCD of 721, 679, 459, 481 is 1
