Greatest Common Divisior

We found the divisors of 30, 7, 71, 59 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 7, 71, 59 is 1.

Therefore, GCD of numbers 30, 7, 71, 59 is 1

Given Input Data is 30, 7, 71, 59

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 7 is 7

Prime Factorization of 71 is 71

Prime Factorization of 59 is 59

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, 7) = 210

GCD(30, 7) = ( 30 x 7 ) / 210

GCD(30, 7) = 210 / 210

GCD(30, 7) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 59

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

LCM(1, 59) = 59

GCD(1, 59) = ( 1 x 59 ) / 59

GCD(1, 59) = 59 / 59

GCD(1, 59) = 1

GCD of 30, 7, 71, 59 is 1
