We found the divisors of 33, 7, 38, 12 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 33, 7, 38, 12 is 1.

Therefore, GCD of numbers 33, 7, 38, 12 is 1

Given Input Data is 33, 7, 38, 12

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 7 is 7

Prime Factorization of 38 is 2 x 19

Prime Factorization of 12 is 2 x 2 x 3

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(33, 7) = 231

GCD(33, 7) = ( 33 x 7 ) / 231

GCD(33, 7) = 231 / 231

GCD(33, 7) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 38

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

LCM(1, 38) = 38

GCD(1, 38) = ( 1 x 38 ) / 38

GCD(1, 38) = 38 / 38

GCD(1, 38) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 12

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

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

GCD(1, 12) = 12 / 12

GCD(1, 12) = 1

GCD of 33, 7, 38, 12 is 1
