Therefore, GCD of numbers 765, 447, 397, 606 is 1

Given Input Data is 765, 447, 397, 606

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

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 447 is 3 x 149

Prime Factorization of 397 is 397

Prime Factorization of 606 is 2 x 3 x 101

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(765, 447) = 113985

GCD(765, 447) = ( 765 x 447 ) / 113985

GCD(765, 447) = 341955 / 113985

GCD(765, 447) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 397

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

LCM(3, 397) = 1191

GCD(3, 397) = ( 3 x 397 ) / 1191

GCD(3, 397) = 1191 / 1191

GCD(3, 397) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 606

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

LCM(1, 606) = 606

GCD(1, 606) = ( 1 x 606 ) / 606

GCD(1, 606) = 606 / 606

GCD(1, 606) = 1

GCD of 765, 447, 397, 606 is 1
