Given Input Data is 294, 270, 47, 861

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

Prime Factorization of 294 is 2 x 3 x 7 x 7

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 47 is 47

Prime Factorization of 861 is 3 x 7 x 41

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(294, 270) = 13230

GCD(294, 270) = ( 294 x 270 ) / 13230

GCD(294, 270) = 79380 / 13230

GCD(294, 270) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 47

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

LCM(6, 47) = 282

GCD(6, 47) = ( 6 x 47 ) / 282

GCD(6, 47) = 282 / 282

GCD(6, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 294, 270, 47, 861 is 1
