Given Input Data is 755, 930, 399, 669

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

Prime Factorization of 755 is 5 x 151

Prime Factorization of 930 is 2 x 3 x 5 x 31

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 669 is 3 x 223

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(755, 930) = 140430

GCD(755, 930) = ( 755 x 930 ) / 140430

GCD(755, 930) = 702150 / 140430

GCD(755, 930) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 399

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

LCM(5, 399) = 1995

GCD(5, 399) = ( 5 x 399 ) / 1995

GCD(5, 399) = 1995 / 1995

GCD(5, 399) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 669

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

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

GCD(1, 669) = 669 / 669

GCD(1, 669) = 1

GCD of 755, 930, 399, 669 is 1
