Greatest Common Divisior

We found the divisors of 30, 85, 47, 50 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 85, 47, 50 is 1.

Therefore, GCD of numbers 30, 85, 47, 50 is 1

Given Input Data is 30, 85, 47, 50

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 85 is 5 x 17

Prime Factorization of 47 is 47

Prime Factorization of 50 is 2 x 5 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(30, 85) = 510

GCD(30, 85) = ( 30 x 85 ) / 510

GCD(30, 85) = 2550 / 510

GCD(30, 85) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 47

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

LCM(5, 47) = 235

GCD(5, 47) = ( 5 x 47 ) / 235

GCD(5, 47) = 235 / 235

GCD(5, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 50

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

LCM(1, 50) = 50

GCD(1, 50) = ( 1 x 50 ) / 50

GCD(1, 50) = 50 / 50

GCD(1, 50) = 1

GCD of 30, 85, 47, 50 is 1
