Given Input Data is 765, 909, 862, 219

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 909 is 3 x 3 x 101

Prime Factorization of 862 is 2 x 431

Prime Factorization of 219 is 3 x 73

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, 909) = 77265

GCD(765, 909) = ( 765 x 909 ) / 77265

GCD(765, 909) = 695385 / 77265

GCD(765, 909) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 862

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

LCM(9, 862) = 7758

GCD(9, 862) = ( 9 x 862 ) / 7758

GCD(9, 862) = 7758 / 7758

GCD(9, 862) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 219

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

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

GCD(1, 219) = 219 / 219

GCD(1, 219) = 1

GCD of 765, 909, 862, 219 is 1
