We found the divisors of 99, 63, 23 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 99, 63, 23 is 1.

Therefore, GCD of numbers 99, 63, 23 is 1

Given Input Data is 99, 63, 23

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

Prime Factorization of 99 is 3 x 3 x 11

Prime Factorization of 63 is 3 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(99, 63) = 693

GCD(99, 63) = ( 99 x 63 ) / 693

GCD(99, 63) = 6237 / 693

GCD(99, 63) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 23

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

LCM(9, 23) = 207

GCD(9, 23) = ( 9 x 23 ) / 207

GCD(9, 23) = 207 / 207

GCD(9, 23) = 1

GCD of 99, 63, 23 is 1
