Greatest Common Divisior

We found the divisors of 85, 34, 38 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 85, 34, 38 is 1.

Therefore, GCD of numbers 85, 34, 38 is 1

Given Input Data is 85, 34, 38

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

Prime Factorization of 85 is 5 x 17

Prime Factorization of 34 is 2 x 17

Prime Factorization of 38 is 2 x 19

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(85, 34) = 170

GCD(85, 34) = ( 85 x 34 ) / 170

GCD(85, 34) = 2890 / 170

GCD(85, 34) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 38

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

LCM(17, 38) = 646

GCD(17, 38) = ( 17 x 38 ) / 646

GCD(17, 38) = 646 / 646

GCD(17, 38) = 1

GCD of 85, 34, 38 is 1
