We found the divisors of 81, 49, 69, 34 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 81, 49, 69, 34 is 1.

Therefore, GCD of numbers 81, 49, 69, 34 is 1

Given Input Data is 81, 49, 69, 34

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

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 69 is 3 x 23

Prime Factorization of 34 is 2 x 17

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(81, 49) = 3969

GCD(81, 49) = ( 81 x 49 ) / 3969

GCD(81, 49) = 3969 / 3969

GCD(81, 49) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 34

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

LCM(1, 34) = 34

GCD(1, 34) = ( 1 x 34 ) / 34

GCD(1, 34) = 34 / 34

GCD(1, 34) = 1

GCD of 81, 49, 69, 34 is 1
