We found the divisors of 80, 38, 79 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 38, 79 is 1.

Therefore, GCD of numbers 80, 38, 79 is 1

Given Input Data is 80, 38, 79

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

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(80, 38) = 1520

GCD(80, 38) = ( 80 x 38 ) / 1520

GCD(80, 38) = 3040 / 1520

GCD(80, 38) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 79

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

LCM(2, 79) = 158

GCD(2, 79) = ( 2 x 79 ) / 158

GCD(2, 79) = 158 / 158

GCD(2, 79) = 1

GCD of 80, 38, 79 is 1
