Given Input Data is 618, 690, 773

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 773 is 773

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(618, 690) = 71070

GCD(618, 690) = ( 618 x 690 ) / 71070

GCD(618, 690) = 426420 / 71070

GCD(618, 690) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 773

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

LCM(6, 773) = 4638

GCD(6, 773) = ( 6 x 773 ) / 4638

GCD(6, 773) = 4638 / 4638

GCD(6, 773) = 1

GCD of 618, 690, 773 is 1
