Given Input Data is 770, 528, 287, 809

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 x 11

Prime Factorization of 287 is 7 x 41

Prime Factorization of 809 is 809

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(770, 528) = 18480

GCD(770, 528) = ( 770 x 528 ) / 18480

GCD(770, 528) = 406560 / 18480

GCD(770, 528) = 22

Step2:

Here we consider the GCD from the above i.e. 22 as first number and the next as 287

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

LCM(22, 287) = 6314

GCD(22, 287) = ( 22 x 287 ) / 6314

GCD(22, 287) = 6314 / 6314

GCD(22, 287) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 809

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

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

GCD(1, 809) = 809 / 809

GCD(1, 809) = 1

GCD of 770, 528, 287, 809 is 1
