Greatest Common Divisior

We found the divisors of 82, 4, 71, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 82, 4, 71, 89 is 1.

Therefore, GCD of numbers 82, 4, 71, 89 is 1

Given Input Data is 82, 4, 71, 89

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

Prime Factorization of 82 is 2 x 41

Prime Factorization of 4 is 2 x 2

Prime Factorization of 71 is 71

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(82, 4) = 164

GCD(82, 4) = ( 82 x 4 ) / 164

GCD(82, 4) = 328 / 164

GCD(82, 4) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 71

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

LCM(2, 71) = 142

GCD(2, 71) = ( 2 x 71 ) / 142

GCD(2, 71) = 142 / 142

GCD(2, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

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

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 82, 4, 71, 89 is 1
