Therefore, GCD of numbers 630, 243, 71, 764 is 1

Given Input Data is 630, 243, 71, 764

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 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 71 is 71

Prime Factorization of 764 is 2 x 2 x 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(630, 243) = 17010

GCD(630, 243) = ( 630 x 243 ) / 17010

GCD(630, 243) = 153090 / 17010

GCD(630, 243) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 71

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

LCM(9, 71) = 639

GCD(9, 71) = ( 9 x 71 ) / 639

GCD(9, 71) = 639 / 639

GCD(9, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 764

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

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

GCD(1, 764) = 764 / 764

GCD(1, 764) = 1

GCD of 630, 243, 71, 764 is 1
