So the Greatest Common Divisior 71, 77, 23 is 1.

Therefore, GCD of numbers 71, 77, 23 is 1

Given Input Data is 71, 77, 23

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

Prime Factorization of 71 is 71

Prime Factorization of 77 is 7 x 11

Prime Factorization of 23 is 23

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, 77) = 5467

GCD(71, 77) = ( 71 x 77 ) / 5467

GCD(71, 77) = 5467 / 5467

GCD(71, 77) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 23

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

LCM(1, 23) = 23

GCD(1, 23) = ( 1 x 23 ) / 23

GCD(1, 23) = 23 / 23

GCD(1, 23) = 1

GCD of 71, 77, 23 is 1
