Greatest Common Divisior

We found the divisors of 14, 6, 69, 81 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 14, 6, 69, 81 is 1.

Therefore, GCD of numbers 14, 6, 69, 81 is 1

Given Input Data is 14, 6, 69, 81

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 6 is 2 x 3

Prime Factorization of 69 is 3 x 23

Prime Factorization of 81 is 3 x 3 x 3 x 3

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(14, 6) = 42

GCD(14, 6) = ( 14 x 6 ) / 42

GCD(14, 6) = 84 / 42

GCD(14, 6) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 69

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

LCM(2, 69) = 138

GCD(2, 69) = ( 2 x 69 ) / 138

GCD(2, 69) = 138 / 138

GCD(2, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

GCD of 14, 6, 69, 81 is 1
