Greatest Common Divisior

We found the divisors of 46, 81, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 46, 81, 72 is 1.

Therefore, GCD of numbers 46, 81, 72 is 1

Given Input Data is 46, 81, 72

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

Prime Factorization of 46 is 2 x 23

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

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

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(46, 81) = 3726

GCD(46, 81) = ( 46 x 81 ) / 3726

GCD(46, 81) = 3726 / 3726

GCD(46, 81) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 72

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

LCM(1, 72) = 72

GCD(1, 72) = ( 1 x 72 ) / 72

GCD(1, 72) = 72 / 72

GCD(1, 72) = 1

GCD of 46, 81, 72 is 1
