**Greatest Common Divisior**

We found the divisors of 60, 45, 99, 51 . The biggest common divisior number is the **GCD** number.

So the **Greatest Common Divisior 60, 45, 99, 51 ** is **3**.

Therefore, GCD of numbers 60, 45, 99, 51 is 3

Given Input Data is 60, 45, 99, 51

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

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 51 is 3 x 17

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(60, 45) = 180

GCD(60, 45) = ( 60 x 45 ) / 180

GCD(60, 45) = 2700 / 180

GCD(60, 45) = 15

**Step2:**

Here we consider the GCD from the above i.e. 15 as first number and the next as 99

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

LCM(15, 99) = 495

GCD(15, 99) = ( 15 x 99 ) / 495

GCD(15, 99) = 1485 / 495

GCD(15, 99) = 3

**Step3:**

Here we consider the GCD from the above i.e. 3 as first number and the next as 51

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

LCM(3, 51) = 51

GCD(3, 51) = ( 3 x 51 ) / 51

GCD(3, 51) = 153 / 51

GCD(3, 51) = 3

GCD of 60, 45, 99, 51 is 3
