Greatest Common Divisior

We found the divisors of 82, 30, 79 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 82, 30, 79 is 1.

Therefore, GCD of numbers 82, 30, 79 is 1

Given Input Data is 82, 30, 79

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

Prime Factorization of 82 is 2 x 41

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 79 is 79

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(82, 30) = 1230

GCD(82, 30) = ( 82 x 30 ) / 1230

GCD(82, 30) = 2460 / 1230

GCD(82, 30) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 79

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

LCM(2, 79) = 158

GCD(2, 79) = ( 2 x 79 ) / 158

GCD(2, 79) = 158 / 158

GCD(2, 79) = 1

GCD of 82, 30, 79 is 1
