Greatest Common Divisior

We found the divisors of 72, 83, 16 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 72, 83, 16 is 1.

Therefore, GCD of numbers 72, 83, 16 is 1

Given Input Data is 72, 83, 16

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

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

Prime Factorization of 83 is 83

Prime Factorization of 16 is 2 x 2 x 2 x 2

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(72, 83) = 5976

GCD(72, 83) = ( 72 x 83 ) / 5976

GCD(72, 83) = 5976 / 5976

GCD(72, 83) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 16

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

LCM(1, 16) = 16

GCD(1, 16) = ( 1 x 16 ) / 16

GCD(1, 16) = 16 / 16

GCD(1, 16) = 1

GCD of 72, 83, 16 is 1
