Greatest Common Divisior

We found the divisors of 69, 63, 71 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 63, 71 is 1.

Therefore, GCD of numbers 69, 63, 71 is 1

Given Input Data is 69, 63, 71

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

Prime Factorization of 69 is 3 x 23

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 71 is 71

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(69, 63) = 1449

GCD(69, 63) = ( 69 x 63 ) / 1449

GCD(69, 63) = 4347 / 1449

GCD(69, 63) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 71

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

LCM(3, 71) = 213

GCD(3, 71) = ( 3 x 71 ) / 213

GCD(3, 71) = 213 / 213

GCD(3, 71) = 1

GCD of 69, 63, 71 is 1
