Greatest Common Divisior

We found the divisors of 43, 12, 69 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 43, 12, 69 is 1.

Therefore, GCD of numbers 43, 12, 69 is 1

Given Input Data is 43, 12, 69

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

Prime Factorization of 43 is 43

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 69 is 3 x 23

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(43, 12) = 516

GCD(43, 12) = ( 43 x 12 ) / 516

GCD(43, 12) = 516 / 516

GCD(43, 12) = 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

GCD of 43, 12, 69 is 1
