Therefore, GCD of numbers 12, 765, 763, 191 is 1

Given Input Data is 12, 765, 763, 191

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

Prime Factorization of 12 is 2 x 2 x 3

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

Prime Factorization of 763 is 7 x 109

Prime Factorization of 191 is 191

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(12, 765) = 3060

GCD(12, 765) = ( 12 x 765 ) / 3060

GCD(12, 765) = 9180 / 3060

GCD(12, 765) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 763

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

LCM(3, 763) = 2289

GCD(3, 763) = ( 3 x 763 ) / 2289

GCD(3, 763) = 2289 / 2289

GCD(3, 763) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 191

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

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

GCD(1, 191) = 191 / 191

GCD(1, 191) = 1

GCD of 12, 765, 763, 191 is 1
