1, 59

Greatest Common Divisior

We found the divisors of 12, 38, 72, 59 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 12, 38, 72, 59 is 1.

Therefore, GCD of numbers 12, 38, 72, 59 is 1

Given Input Data is 12, 38, 72, 59

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 38 is 2 x 19

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

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(12, 38) = 228

GCD(12, 38) = ( 12 x 38 ) / 228

GCD(12, 38) = 456 / 228

GCD(12, 38) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 72

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

LCM(2, 72) = 72

GCD(2, 72) = ( 2 x 72 ) / 72

GCD(2, 72) = 144 / 72

GCD(2, 72) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 59

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

LCM(2, 59) = 118

GCD(2, 59) = ( 2 x 59 ) / 118

GCD(2, 59) = 118 / 118

GCD(2, 59) = 1

GCD of 12, 38, 72, 59 is 1
