Greatest Common Divisior

We found the divisors of 47, 34, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 34, 30 is 1.

Therefore, GCD of numbers 47, 34, 30 is 1

Given Input Data is 47, 34, 30

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

Prime Factorization of 47 is 47

Prime Factorization of 34 is 2 x 17

Prime Factorization of 30 is 2 x 3 x 5

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(47, 34) = 1598

GCD(47, 34) = ( 47 x 34 ) / 1598

GCD(47, 34) = 1598 / 1598

GCD(47, 34) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

GCD of 47, 34, 30 is 1
