Therefore, GCD of numbers 77, 154, 317, 865 is 1

Given Input Data is 77, 154, 317, 865

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 317 is 317

Prime Factorization of 865 is 5 x 173

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(77, 154) = 154

GCD(77, 154) = ( 77 x 154 ) / 154

GCD(77, 154) = 11858 / 154

GCD(77, 154) = 77

Step2:

Here we consider the GCD from the above i.e. 77 as first number and the next as 317

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

LCM(77, 317) = 24409

GCD(77, 317) = ( 77 x 317 ) / 24409

GCD(77, 317) = 24409 / 24409

GCD(77, 317) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 865

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

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

GCD(1, 865) = 865 / 865

GCD(1, 865) = 1

GCD of 77, 154, 317, 865 is 1
