Greatest Common Divisior

We found the divisors of 65, 71, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 65, 71, 17 is 1.

Therefore, GCD of numbers 65, 71, 17 is 1

Given Input Data is 65, 71, 17

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

Prime Factorization of 65 is 5 x 13

Prime Factorization of 71 is 71

Prime Factorization of 17 is 17

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(65, 71) = 4615

GCD(65, 71) = ( 65 x 71 ) / 4615

GCD(65, 71) = 4615 / 4615

GCD(65, 71) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 17

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

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

GCD(1, 17) = 17 / 17

GCD(1, 17) = 1

GCD of 65, 71, 17 is 1
