Greatest Common Divisior

We found the divisors of 58, 78, 13 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 58, 78, 13 is 1.

Therefore, GCD of numbers 58, 78, 13 is 1

Given Input Data is 58, 78, 13

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

Prime Factorization of 58 is 2 x 29

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 13 is 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(58, 78) = 2262

GCD(58, 78) = ( 58 x 78 ) / 2262

GCD(58, 78) = 4524 / 2262

GCD(58, 78) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 13

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

LCM(2, 13) = 26

GCD(2, 13) = ( 2 x 13 ) / 26

GCD(2, 13) = 26 / 26

GCD(2, 13) = 1

GCD of 58, 78, 13 is 1
