We found the divisors of 71, 43, 39 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 43, 39 is 1.

Therefore, GCD of numbers 71, 43, 39 is 1

Given Input Data is 71, 43, 39

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

Prime Factorization of 71 is 71

Prime Factorization of 43 is 43

Prime Factorization of 39 is 3 x 13

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(71, 43) = 3053

GCD(71, 43) = ( 71 x 43 ) / 3053

GCD(71, 43) = 3053 / 3053

GCD(71, 43) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 39

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

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

GCD(1, 39) = 39 / 39

GCD(1, 39) = 1

GCD of 71, 43, 39 is 1
