Therefore, GCD of numbers 170, 430, 81, 512 is 1

Given Input Data is 170, 430, 81, 512

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

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 512 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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(170, 430) = 7310

GCD(170, 430) = ( 170 x 430 ) / 7310

GCD(170, 430) = 73100 / 7310

GCD(170, 430) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 81

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

LCM(10, 81) = 810

GCD(10, 81) = ( 10 x 81 ) / 810

GCD(10, 81) = 810 / 810

GCD(10, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 512

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

LCM(1, 512) = 512

GCD(1, 512) = ( 1 x 512 ) / 512

GCD(1, 512) = 512 / 512

GCD(1, 512) = 1

GCD of 170, 430, 81, 512 is 1
