Greatest Common Divisior

We found the divisors of 86, 81, 79, 11 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 86, 81, 79, 11 is 1.

Therefore, GCD of numbers 86, 81, 79, 11 is 1

Given Input Data is 86, 81, 79, 11

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

Prime Factorization of 86 is 2 x 43

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

Prime Factorization of 79 is 79

Prime Factorization of 11 is 11

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(86, 81) = 6966

GCD(86, 81) = ( 86 x 81 ) / 6966

GCD(86, 81) = 6966 / 6966

GCD(86, 81) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 79

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

LCM(1, 79) = 79

GCD(1, 79) = ( 1 x 79 ) / 79

GCD(1, 79) = 79 / 79

GCD(1, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 11

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

LCM(1, 11) = 11

GCD(1, 11) = ( 1 x 11 ) / 11

GCD(1, 11) = 11 / 11

GCD(1, 11) = 1

GCD of 86, 81, 79, 11 is 1
