Greatest Common Divisior

We found the divisors of 52, 81, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 52, 81, 30 is 1.

Therefore, GCD of numbers 52, 81, 30 is 1

Given Input Data is 52, 81, 30

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

Prime Factorization of 52 is 2 x 2 x 13

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 30 is 2 x 3 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(52, 81) = 4212

GCD(52, 81) = ( 52 x 81 ) / 4212

GCD(52, 81) = 4212 / 4212

GCD(52, 81) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

GCD of 52, 81, 30 is 1
