**Greatest Common Divisior**

We found the divisors of 93, 3, 30, 42 . The biggest common divisior number is the **GCD** number.

So the **Greatest Common Divisior 93, 3, 30, 42 ** is **3**.

Therefore, GCD of numbers 93, 3, 30, 42 is 3

Given Input Data is 93, 3, 30, 42

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

Prime Factorization of 93 is 3 x 31

Prime Factorization of 3 is 3

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 42 is 2 x 3 x 7

Highest common occurrences in the given inputs are 3^{1}

Multiplying them we get the GCD as 3

**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(93, 3) = 93

GCD(93, 3) = ( 93 x 3 ) / 93

GCD(93, 3) = 279 / 93

GCD(93, 3) = 3

**Step2:**

Here we consider the GCD from the above i.e. 3 as first number and the next as 30

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

LCM(3, 30) = 30

GCD(3, 30) = ( 3 x 30 ) / 30

GCD(3, 30) = 90 / 30

GCD(3, 30) = 3

**Step3:**

Here we consider the GCD from the above i.e. 3 as first number and the next as 42

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

LCM(3, 42) = 42

GCD(3, 42) = ( 3 x 42 ) / 42

GCD(3, 42) = 126 / 42

GCD(3, 42) = 3

GCD of 93, 3, 30, 42 is 3
