Greatest Common Divisior

We found the divisors of 40, 82, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 82, 89 is 1.

Therefore, GCD of numbers 40, 82, 89 is 1

Given Input Data is 40, 82, 89

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

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 82 is 2 x 41

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(40, 82) = 1640

GCD(40, 82) = ( 40 x 82 ) / 1640

GCD(40, 82) = 3280 / 1640

GCD(40, 82) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 89

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

LCM(2, 89) = 178

GCD(2, 89) = ( 2 x 89 ) / 178

GCD(2, 89) = 178 / 178

GCD(2, 89) = 1

GCD of 40, 82, 89 is 1
