So the Greatest Common Divisior 71, 63, 79 is 1.

Therefore, GCD of numbers 71, 63, 79 is 1

Given Input Data is 71, 63, 79

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

Prime Factorization of 71 is 71

Prime Factorization of 63 is 3 x 3 x 7

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(71, 63) = 4473

GCD(71, 63) = ( 71 x 63 ) / 4473

GCD(71, 63) = 4473 / 4473

GCD(71, 63) = 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 71, 63, 79 is 1
