We found the divisors of 430, 206, 230, 985 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 430, 206, 230, 985 is 1.

Therefore, GCD of numbers 430, 206, 230, 985 is 1

Given Input Data is 430, 206, 230, 985

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

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 206 is 2 x 103

Prime Factorization of 230 is 2 x 5 x 23

Prime Factorization of 985 is 5 x 197

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(430, 206) = 44290

GCD(430, 206) = ( 430 x 206 ) / 44290

GCD(430, 206) = 88580 / 44290

GCD(430, 206) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 230

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

LCM(2, 230) = 230

GCD(2, 230) = ( 2 x 230 ) / 230

GCD(2, 230) = 460 / 230

GCD(2, 230) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 985

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

LCM(2, 985) = 1970

GCD(2, 985) = ( 2 x 985 ) / 1970

GCD(2, 985) = 1970 / 1970

GCD(2, 985) = 1

GCD of 430, 206, 230, 985 is 1
