Greatest Common Divisior

We found the divisors of 39, 30, 49 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 39, 30, 49 is 1.

Therefore, GCD of numbers 39, 30, 49 is 1

Given Input Data is 39, 30, 49

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 49 is 7 x 7

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, 30) = 390

GCD(39, 30) = ( 39 x 30 ) / 390

GCD(39, 30) = 1170 / 390

GCD(39, 30) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 49

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

LCM(3, 49) = 147

GCD(3, 49) = ( 3 x 49 ) / 147

GCD(3, 49) = 147 / 147

GCD(3, 49) = 1

GCD of 39, 30, 49 is 1
