Greatest Common Divisior

We found the divisors of 67, 6, 12, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 67, 6, 12, 30 is 1.

Therefore, GCD of numbers 67, 6, 12, 30 is 1

Given Input Data is 67, 6, 12, 30

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

Prime Factorization of 67 is 67

Prime Factorization of 6 is 2 x 3

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 30 is 2 x 3 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(67, 6) = 402

GCD(67, 6) = ( 67 x 6 ) / 402

GCD(67, 6) = 402 / 402

GCD(67, 6) = 1

Step2:

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

Step3:

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

GCD of 67, 6, 12, 30 is 1
