Given Input Data is 845, 315, 297, 618

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

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 297 is 3 x 3 x 3 x 11

Prime Factorization of 618 is 2 x 3 x 103

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(845, 315) = 53235

GCD(845, 315) = ( 845 x 315 ) / 53235

GCD(845, 315) = 266175 / 53235

GCD(845, 315) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 297

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

LCM(5, 297) = 1485

GCD(5, 297) = ( 5 x 297 ) / 1485

GCD(5, 297) = 1485 / 1485

GCD(5, 297) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 618

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

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

GCD(1, 618) = 618 / 618

GCD(1, 618) = 1

GCD of 845, 315, 297, 618 is 1
