Therefore, GCD of numbers 865, 170, 104 is 1

Given Input Data is 865, 170, 104

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 170 is 2 x 5 x 17

Prime Factorization of 104 is 2 x 2 x 2 x 13

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, 170) = 29410

GCD(865, 170) = ( 865 x 170 ) / 29410

GCD(865, 170) = 147050 / 29410

GCD(865, 170) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 104

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

LCM(5, 104) = 520

GCD(5, 104) = ( 5 x 104 ) / 520

GCD(5, 104) = 520 / 520

GCD(5, 104) = 1

GCD of 865, 170, 104 is 1
