Greatest Common Divisior

We found the divisors of 64, 47, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 64, 47, 65 is 1.

Therefore, GCD of numbers 64, 47, 65 is 1

Given Input Data is 64, 47, 65

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

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 47 is 47

Prime Factorization of 65 is 5 x 13

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(64, 47) = 3008

GCD(64, 47) = ( 64 x 47 ) / 3008

GCD(64, 47) = 3008 / 3008

GCD(64, 47) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

GCD of 64, 47, 65 is 1
