Therefore, GCD of numbers 630, 468, 78, 835 is 1

Given Input Data is 630, 468, 78, 835

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

Prime Factorization of 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 468 is 2 x 2 x 3 x 3 x 13

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 835 is 5 x 167

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(630, 468) = 16380

GCD(630, 468) = ( 630 x 468 ) / 16380

GCD(630, 468) = 294840 / 16380

GCD(630, 468) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 78

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

LCM(18, 78) = 234

GCD(18, 78) = ( 18 x 78 ) / 234

GCD(18, 78) = 1404 / 234

GCD(18, 78) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 835

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

LCM(6, 835) = 5010

GCD(6, 835) = ( 6 x 835 ) / 5010

GCD(6, 835) = 5010 / 5010

GCD(6, 835) = 1

GCD of 630, 468, 78, 835 is 1
