Finding GCD of 48, 21, 23 using Prime Factorization

Given Input Data is 48, 21, 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 21 is 3 x 7

Prime Factorization of 23 is 23

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 48, 21, 23 using LCM Formula

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, 21) = 336

GCD(48, 21) = ( 48 x 21 ) / 336

GCD(48, 21) = 1008 / 336

GCD(48, 21) = 3


Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 23

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

LCM(3, 23) = 69

GCD(3, 23) = ( 3 x 23 ) / 69

GCD(3, 23) = 69 / 69

GCD(3, 23) = 1

GCD of 48, 21, 23 is 1
