Greatest Common Divisior

We found the divisors of 47, 91, 68 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 47, 91, 68 is 1.

Therefore, GCD of numbers 47, 91, 68 is 1

Given Input Data is 47, 91, 68

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

Prime Factorization of 47 is 47

Prime Factorization of 91 is 7 x 13

Prime Factorization of 68 is 2 x 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(47, 91) = 4277

GCD(47, 91) = ( 47 x 91 ) / 4277

GCD(47, 91) = 4277 / 4277

GCD(47, 91) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 68

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

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

GCD(1, 68) = 68 / 68

GCD(1, 68) = 1

GCD of 47, 91, 68 is 1
