Given Input Data is 245, 390, 845, 126

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 845 is 5 x 13 x 13

Prime Factorization of 126 is 2 x 3 x 3 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(245, 390) = 19110

GCD(245, 390) = ( 245 x 390 ) / 19110

GCD(245, 390) = 95550 / 19110

GCD(245, 390) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 845

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

LCM(5, 845) = 845

GCD(5, 845) = ( 5 x 845 ) / 845

GCD(5, 845) = 4225 / 845

GCD(5, 845) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 126

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

LCM(5, 126) = 630

GCD(5, 126) = ( 5 x 126 ) / 630

GCD(5, 126) = 630 / 630

GCD(5, 126) = 1

GCD of 245, 390, 845, 126 is 1
