Therefore, GCD of numbers 392, 399, 23 is 1

Given Input Data is 392, 399, 23

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

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 399 is 3 x 7 x 19

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(392, 399) = 22344

GCD(392, 399) = ( 392 x 399 ) / 22344

GCD(392, 399) = 156408 / 22344

GCD(392, 399) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 23

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

LCM(7, 23) = 161

GCD(7, 23) = ( 7 x 23 ) / 161

GCD(7, 23) = 161 / 161

GCD(7, 23) = 1

GCD of 392, 399, 23 is 1
