Given Input Data is 930, 190, 15, 231

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

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

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 15 is 3 x 5

Prime Factorization of 231 is 3 x 7 x 11

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(930, 190) = 17670

GCD(930, 190) = ( 930 x 190 ) / 17670

GCD(930, 190) = 176700 / 17670

GCD(930, 190) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 15

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

LCM(10, 15) = 30

GCD(10, 15) = ( 10 x 15 ) / 30

GCD(10, 15) = 150 / 30

GCD(10, 15) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 231

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

LCM(5, 231) = 1155

GCD(5, 231) = ( 5 x 231 ) / 1155

GCD(5, 231) = 1155 / 1155

GCD(5, 231) = 1

GCD of 930, 190, 15, 231 is 1
