So the Greatest Common Divisior 77, 41, 39 is 1.

Therefore, GCD of numbers 77, 41, 39 is 1

Given Input Data is 77, 41, 39

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 41 is 41

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(77, 41) = 3157

GCD(77, 41) = ( 77 x 41 ) / 3157

GCD(77, 41) = 3157 / 3157

GCD(77, 41) = 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 77, 41, 39 is 1
