Given Input Data is 18, 315, 930, 434

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

Prime Factorization of 18 is 2 x 3 x 3

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

Prime Factorization of 930 is 2 x 3 x 5 x 31

Prime Factorization of 434 is 2 x 7 x 31

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(18, 315) = 630

GCD(18, 315) = ( 18 x 315 ) / 630

GCD(18, 315) = 5670 / 630

GCD(18, 315) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 930

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

LCM(9, 930) = 2790

GCD(9, 930) = ( 9 x 930 ) / 2790

GCD(9, 930) = 8370 / 2790

GCD(9, 930) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 434

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

LCM(3, 434) = 1302

GCD(3, 434) = ( 3 x 434 ) / 1302

GCD(3, 434) = 1302 / 1302

GCD(3, 434) = 1

GCD of 18, 315, 930, 434 is 1
