Given Input Data is 915, 618, 852, 245

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

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 852 is 2 x 2 x 3 x 71

Prime Factorization of 245 is 5 x 7 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(915, 618) = 188490

GCD(915, 618) = ( 915 x 618 ) / 188490

GCD(915, 618) = 565470 / 188490

GCD(915, 618) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 852

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

LCM(3, 852) = 852

GCD(3, 852) = ( 3 x 852 ) / 852

GCD(3, 852) = 2556 / 852

GCD(3, 852) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 245

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

LCM(3, 245) = 735

GCD(3, 245) = ( 3 x 245 ) / 735

GCD(3, 245) = 735 / 735

GCD(3, 245) = 1

GCD of 915, 618, 852, 245 is 1
