Greatest Common Divisior

We found the divisors of 13, 47, 25 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 13, 47, 25 is 1.

Therefore, GCD of numbers 13, 47, 25 is 1

Given Input Data is 13, 47, 25

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

Prime Factorization of 13 is 13

Prime Factorization of 47 is 47

Prime Factorization of 25 is 5 x 5

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(13, 47) = 611

GCD(13, 47) = ( 13 x 47 ) / 611

GCD(13, 47) = 611 / 611

GCD(13, 47) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 25

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

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

GCD(1, 25) = 25 / 25

GCD(1, 25) = 1

GCD of 13, 47, 25 is 1
