Given Input Data is 423, 858, 385, 230

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

Prime Factorization of 423 is 3 x 3 x 47

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 230 is 2 x 5 x 23

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(423, 858) = 120978

GCD(423, 858) = ( 423 x 858 ) / 120978

GCD(423, 858) = 362934 / 120978

GCD(423, 858) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 385

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

LCM(3, 385) = 1155

GCD(3, 385) = ( 3 x 385 ) / 1155

GCD(3, 385) = 1155 / 1155

GCD(3, 385) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 230

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

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

GCD(1, 230) = 230 / 230

GCD(1, 230) = 1

GCD of 423, 858, 385, 230 is 1
