Greatest Common Divisior

We found the divisors of 9, 65, 84 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 9, 65, 84 is 1.

Therefore, GCD of numbers 9, 65, 84 is 1

Given Input Data is 9, 65, 84

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

Prime Factorization of 9 is 3 x 3

Prime Factorization of 65 is 5 x 13

Prime Factorization of 84 is 2 x 2 x 3 x 7

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(9, 65) = 585

GCD(9, 65) = ( 9 x 65 ) / 585

GCD(9, 65) = 585 / 585

GCD(9, 65) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 84

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

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

GCD(1, 84) = 84 / 84

GCD(1, 84) = 1

GCD of 9, 65, 84 is 1
