So the Greatest Common Divisior 83, 23, 78 is 1.

Therefore, GCD of numbers 83, 23, 78 is 1

Given Input Data is 83, 23, 78

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

Prime Factorization of 83 is 83

Prime Factorization of 23 is 23

Prime Factorization of 78 is 2 x 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(83, 23) = 1909

GCD(83, 23) = ( 83 x 23 ) / 1909

GCD(83, 23) = 1909 / 1909

GCD(83, 23) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

GCD of 83, 23, 78 is 1
