Greatest Common Divisior

We found the divisors of 99, 6, 40, 79 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 99, 6, 40, 79 is 1.

Therefore, GCD of numbers 99, 6, 40, 79 is 1

Given Input Data is 99, 6, 40, 79

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

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 6 is 2 x 3

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 79 is 79

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(99, 6) = 198

GCD(99, 6) = ( 99 x 6 ) / 198

GCD(99, 6) = 594 / 198

GCD(99, 6) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 40

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

LCM(3, 40) = 120

GCD(3, 40) = ( 3 x 40 ) / 120

GCD(3, 40) = 120 / 120

GCD(3, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

GCD of 99, 6, 40, 79 is 1
