Greatest Common Divisior

We found the divisors of 11, 89, 91, 84 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 11, 89, 91, 84 is 1.

Therefore, GCD of numbers 11, 89, 91, 84 is 1

Given Input Data is 11, 89, 91, 84

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

Prime Factorization of 11 is 11

Prime Factorization of 89 is 89

Prime Factorization of 91 is 7 x 13

Prime Factorization of 84 is 2 x 2 x 3 x 7

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(11, 89) = 979

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

GCD(11, 89) = 979 / 979

GCD(11, 89) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 84

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

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

GCD(1, 84) = 84 / 84

GCD(1, 84) = 1

GCD of 11, 89, 91, 84 is 1
