Greatest Common Divisior

We found the divisors of 80, 76, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 76, 89 is 1.

Therefore, GCD of numbers 80, 76, 89 is 1

Given Input Data is 80, 76, 89

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 89 is 89

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(80, 76) = 1520

GCD(80, 76) = ( 80 x 76 ) / 1520

GCD(80, 76) = 6080 / 1520

GCD(80, 76) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 89

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

LCM(4, 89) = 356

GCD(4, 89) = ( 4 x 89 ) / 356

GCD(4, 89) = 356 / 356

GCD(4, 89) = 1

GCD of 80, 76, 89 is 1
