Greatest Common Divisior

We found the divisors of 4, 72, 99 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 4, 72, 99 is 1.

Therefore, GCD of numbers 4, 72, 99 is 1

Given Input Data is 4, 72, 99

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

Prime Factorization of 4 is 2 x 2

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 99 is 3 x 3 x 11

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(4, 72) = 72

GCD(4, 72) = ( 4 x 72 ) / 72

GCD(4, 72) = 288 / 72

GCD(4, 72) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 99

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

LCM(4, 99) = 396

GCD(4, 99) = ( 4 x 99 ) / 396

GCD(4, 99) = 396 / 396

GCD(4, 99) = 1

GCD of 4, 72, 99 is 1
