Greatest Common Divisior

We found the divisors of 39, 25, 17 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 39, 25, 17 is 1.

Therefore, GCD of numbers 39, 25, 17 is 1

Given Input Data is 39, 25, 17

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 25 is 5 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(39, 25) = 975

GCD(39, 25) = ( 39 x 25 ) / 975

GCD(39, 25) = 975 / 975

GCD(39, 25) = 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 39, 25, 17 is 1
