Greatest Common Divisior

We found the divisors of 30, 84, 67, 32 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 84, 67, 32 is 1.

Therefore, GCD of numbers 30, 84, 67, 32 is 1

Given Input Data is 30, 84, 67, 32

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 84 is 2 x 2 x 3 x 7

Prime Factorization of 67 is 67

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

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, 84) = 420

GCD(30, 84) = ( 30 x 84 ) / 420

GCD(30, 84) = 2520 / 420

GCD(30, 84) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 67

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

LCM(6, 67) = 402

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

GCD(6, 67) = 402 / 402

GCD(6, 67) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 32

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

LCM(1, 32) = 32

GCD(1, 32) = ( 1 x 32 ) / 32

GCD(1, 32) = 32 / 32

GCD(1, 32) = 1

GCD of 30, 84, 67, 32 is 1
