We found the divisors of 48, 42, 23 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 48, 42, 23 is 1.

Therefore, GCD of numbers 48, 42, 23 is 1

Given Input Data is 48, 42, 23

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

Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3

Prime Factorization of 42 is 2 x 3 x 7

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(48, 42) = 336

GCD(48, 42) = ( 48 x 42 ) / 336

GCD(48, 42) = 2016 / 336

GCD(48, 42) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 23

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

LCM(6, 23) = 138

GCD(6, 23) = ( 6 x 23 ) / 138

GCD(6, 23) = 138 / 138

GCD(6, 23) = 1

GCD of 48, 42, 23 is 1
