Given Input Data is 393, 630, 611

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

Prime Factorization of 393 is 3 x 131

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

Prime Factorization of 611 is 13 x 47

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(393, 630) = 82530

GCD(393, 630) = ( 393 x 630 ) / 82530

GCD(393, 630) = 247590 / 82530

GCD(393, 630) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 611

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

LCM(3, 611) = 1833

GCD(3, 611) = ( 3 x 611 ) / 1833

GCD(3, 611) = 1833 / 1833

GCD(3, 611) = 1

GCD of 393, 630, 611 is 1
