Greatest Common Divisior

We found the divisors of 39, 4, 30, 95 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 39, 4, 30, 95 is 1.

Therefore, GCD of numbers 39, 4, 30, 95 is 1

Given Input Data is 39, 4, 30, 95

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 4 is 2 x 2

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 95 is 5 x 19

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, 4) = 156

GCD(39, 4) = ( 39 x 4 ) / 156

GCD(39, 4) = 156 / 156

GCD(39, 4) = 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

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 95

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

LCM(1, 95) = 95

GCD(1, 95) = ( 1 x 95 ) / 95

GCD(1, 95) = 95 / 95

GCD(1, 95) = 1

GCD of 39, 4, 30, 95 is 1
