Greatest Common Divisior

We found the divisors of 86, 40, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 40, 17 is 1.

Therefore, GCD of numbers 86, 40, 17 is 1

Given Input Data is 86, 40, 17

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

Prime Factorization of 86 is 2 x 43

Prime Factorization of 40 is 2 x 2 x 2 x 5

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(86, 40) = 1720

GCD(86, 40) = ( 86 x 40 ) / 1720

GCD(86, 40) = 3440 / 1720

GCD(86, 40) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 17

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

LCM(2, 17) = 34

GCD(2, 17) = ( 2 x 17 ) / 34

GCD(2, 17) = 34 / 34

GCD(2, 17) = 1

GCD of 86, 40, 17 is 1
