Greatest Common Divisior

We found the divisors of 81, 16, 67 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 81, 16, 67 is 1.

Therefore, GCD of numbers 81, 16, 67 is 1

Given Input Data is 81, 16, 67

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

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

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

Prime Factorization of 67 is 67

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(81, 16) = 1296

GCD(81, 16) = ( 81 x 16 ) / 1296

GCD(81, 16) = 1296 / 1296

GCD(81, 16) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 67

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

LCM(1, 67) = 67

GCD(1, 67) = ( 1 x 67 ) / 67

GCD(1, 67) = 67 / 67

GCD(1, 67) = 1

GCD of 81, 16, 67 is 1
