We found the divisors of 239, 100, 109, 430 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 239, 100, 109, 430 is 1.

Therefore, GCD of numbers 239, 100, 109, 430 is 1

Given Input Data is 239, 100, 109, 430

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

Prime Factorization of 239 is 239

Prime Factorization of 100 is 2 x 2 x 5 x 5

Prime Factorization of 109 is 109

Prime Factorization of 430 is 2 x 5 x 43

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(239, 100) = 23900

GCD(239, 100) = ( 239 x 100 ) / 23900

GCD(239, 100) = 23900 / 23900

GCD(239, 100) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 109

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

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

GCD(1, 109) = 109 / 109

GCD(1, 109) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 430

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

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

GCD(1, 430) = 430 / 430

GCD(1, 430) = 1

GCD of 239, 100, 109, 430 is 1
