Therefore, GCD of numbers 306, 289, 679, 447 is 1

Given Input Data is 306, 289, 679, 447

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

Prime Factorization of 306 is 2 x 3 x 3 x 17

Prime Factorization of 289 is 17 x 17

Prime Factorization of 679 is 7 x 97

Prime Factorization of 447 is 3 x 149

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(306, 289) = 5202

GCD(306, 289) = ( 306 x 289 ) / 5202

GCD(306, 289) = 88434 / 5202

GCD(306, 289) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 679

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

LCM(17, 679) = 11543

GCD(17, 679) = ( 17 x 679 ) / 11543

GCD(17, 679) = 11543 / 11543

GCD(17, 679) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 447

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

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

GCD(1, 447) = 447 / 447

GCD(1, 447) = 1

GCD of 306, 289, 679, 447 is 1
