Therefore, GCD of numbers 865, 545, 586, 856 is 1

Given Input Data is 865, 545, 586, 856

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 545 is 5 x 109

Prime Factorization of 586 is 2 x 293

Prime Factorization of 856 is 2 x 2 x 2 x 107

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(865, 545) = 94285

GCD(865, 545) = ( 865 x 545 ) / 94285

GCD(865, 545) = 471425 / 94285

GCD(865, 545) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 586

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

LCM(5, 586) = 2930

GCD(5, 586) = ( 5 x 586 ) / 2930

GCD(5, 586) = 2930 / 2930

GCD(5, 586) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 856

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

LCM(1, 856) = 856

GCD(1, 856) = ( 1 x 856 ) / 856

GCD(1, 856) = 856 / 856

GCD(1, 856) = 1

GCD of 865, 545, 586, 856 is 1
