So the Greatest Common Divisior 39, 38, 79 is 1.

Therefore, GCD of numbers 39, 38, 79 is 1

Given Input Data is 39, 38, 79

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 38 is 2 x 19

Prime Factorization of 79 is 79

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(39, 38) = 1482

GCD(39, 38) = ( 39 x 38 ) / 1482

GCD(39, 38) = 1482 / 1482

GCD(39, 38) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

GCD of 39, 38, 79 is 1
