Greatest Common Divisior

We found the divisors of 63, 28, 34 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 63, 28, 34 is 1.

Therefore, GCD of numbers 63, 28, 34 is 1

Given Input Data is 63, 28, 34

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 34 is 2 x 17

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(63, 28) = 252

GCD(63, 28) = ( 63 x 28 ) / 252

GCD(63, 28) = 1764 / 252

GCD(63, 28) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 34

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

LCM(7, 34) = 238

GCD(7, 34) = ( 7 x 34 ) / 238

GCD(7, 34) = 238 / 238

GCD(7, 34) = 1

GCD of 63, 28, 34 is 1
