Greatest Common Divisior

We found the divisors of 20, 41, 86 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 20, 41, 86 is 1.

Therefore, GCD of numbers 20, 41, 86 is 1

Given Input Data is 20, 41, 86

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

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 41 is 41

Prime Factorization of 86 is 2 x 43

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(20, 41) = 820

GCD(20, 41) = ( 20 x 41 ) / 820

GCD(20, 41) = 820 / 820

GCD(20, 41) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 86

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

LCM(1, 86) = 86

GCD(1, 86) = ( 1 x 86 ) / 86

GCD(1, 86) = 86 / 86

GCD(1, 86) = 1

GCD of 20, 41, 86 is 1
