Greatest Common Divisior

We found the divisors of 14, 20, 40 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 14, 20, 40 is 2.

Therefore, GCD of numbers 14, 20, 40 is 2

Given Input Data is 14, 20, 40

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 20 is 2 x 2 x 5

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

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(14, 20) = 140

GCD(14, 20) = ( 14 x 20 ) / 140

GCD(14, 20) = 280 / 140

GCD(14, 20) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 40

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

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

GCD(2, 40) = 80 / 40

GCD(2, 40) = 2

GCD of 14, 20, 40 is 2
