Given Input Data is 287, 294, 19, 216

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

Prime Factorization of 287 is 7 x 41

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

Prime Factorization of 19 is 19

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

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(287, 294) = 12054

GCD(287, 294) = ( 287 x 294 ) / 12054

GCD(287, 294) = 84378 / 12054

GCD(287, 294) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 19

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

LCM(7, 19) = 133

GCD(7, 19) = ( 7 x 19 ) / 133

GCD(7, 19) = 133 / 133

GCD(7, 19) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 216

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

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

GCD(1, 216) = 216 / 216

GCD(1, 216) = 1

GCD of 287, 294, 19, 216 is 1
