We found the divisors of 430, 207, 811, 385 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 430, 207, 811, 385 is 1.

Therefore, GCD of numbers 430, 207, 811, 385 is 1

Given Input Data is 430, 207, 811, 385

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 207 is 3 x 3 x 23

Prime Factorization of 811 is 811

Prime Factorization of 385 is 5 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(430, 207) = 89010

GCD(430, 207) = ( 430 x 207 ) / 89010

GCD(430, 207) = 89010 / 89010

GCD(430, 207) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 385

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

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

GCD(1, 385) = 385 / 385

GCD(1, 385) = 1

GCD of 430, 207, 811, 385 is 1
