Therefore, GCD of numbers 207, 231, 807, 256 is 1

Given Input Data is 207, 231, 807, 256

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 231 is 3 x 7 x 11

Prime Factorization of 807 is 3 x 269

Prime Factorization of 256 is 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(207, 231) = 15939

GCD(207, 231) = ( 207 x 231 ) / 15939

GCD(207, 231) = 47817 / 15939

GCD(207, 231) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 807

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

LCM(3, 807) = 807

GCD(3, 807) = ( 3 x 807 ) / 807

GCD(3, 807) = 2421 / 807

GCD(3, 807) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 256

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

LCM(3, 256) = 768

GCD(3, 256) = ( 3 x 256 ) / 768

GCD(3, 256) = 768 / 768

GCD(3, 256) = 1

GCD of 207, 231, 807, 256 is 1
