Greatest Common Divisior

We found the divisors of 50, 20, 80 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 50, 20, 80 is 10.

Therefore, GCD of numbers 50, 20, 80 is 10

Given Input Data is 50, 20, 80

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

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Highest common occurrences in the given inputs are 2¹ x 5¹

Multiplying them we get the GCD as 10

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(50, 20) = 100

GCD(50, 20) = ( 50 x 20 ) / 100

GCD(50, 20) = 1000 / 100

GCD(50, 20) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 80

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

LCM(10, 80) = 80

GCD(10, 80) = ( 10 x 80 ) / 80

GCD(10, 80) = 800 / 80

GCD(10, 80) = 10

GCD of 50, 20, 80 is 10
