Therefore, GCD of numbers 385, 210, 97, 630 is 1

Given Input Data is 385, 210, 97, 630

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 97 is 97

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

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(385, 210) = 2310

GCD(385, 210) = ( 385 x 210 ) / 2310

GCD(385, 210) = 80850 / 2310

GCD(385, 210) = 35

Step2:

Here we consider the GCD from the above i.e. 35 as first number and the next as 97

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

LCM(35, 97) = 3395

GCD(35, 97) = ( 35 x 97 ) / 3395

GCD(35, 97) = 3395 / 3395

GCD(35, 97) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 630

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

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

GCD(1, 630) = 630 / 630

GCD(1, 630) = 1

GCD of 385, 210, 97, 630 is 1
