So the Greatest Common Divisior 815, 963, 671, 190 is 1.

Therefore, GCD of numbers 815, 963, 671, 190 is 1

Given Input Data is 815, 963, 671, 190

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 671 is 11 x 61

Prime Factorization of 190 is 2 x 5 x 19

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(815, 963) = 784845

GCD(815, 963) = ( 815 x 963 ) / 784845

GCD(815, 963) = 784845 / 784845

GCD(815, 963) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 671

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

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

GCD(1, 671) = 671 / 671

GCD(1, 671) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 190

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

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

GCD(1, 190) = 190 / 190

GCD(1, 190) = 1

GCD of 815, 963, 671, 190 is 1
