Greatest Common Divisior

We found the divisors of 89, 11, 78 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 89, 11, 78 is 1.

Therefore, GCD of numbers 89, 11, 78 is 1

Given Input Data is 89, 11, 78

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

Prime Factorization of 89 is 89

Prime Factorization of 11 is 11

Prime Factorization of 78 is 2 x 3 x 13

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(89, 11) = 979

GCD(89, 11) = ( 89 x 11 ) / 979

GCD(89, 11) = 979 / 979

GCD(89, 11) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

GCD of 89, 11, 78 is 1
