Greatest Common Divisior

We found the divisors of 40, 44, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 44, 15 is 1.

Therefore, GCD of numbers 40, 44, 15 is 1

Given Input Data is 40, 44, 15

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 44 is 2 x 2 x 11

Prime Factorization of 15 is 3 x 5

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, 44) = 440

GCD(40, 44) = ( 40 x 44 ) / 440

GCD(40, 44) = 1760 / 440

GCD(40, 44) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 15

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

LCM(4, 15) = 60

GCD(4, 15) = ( 4 x 15 ) / 60

GCD(4, 15) = 60 / 60

GCD(4, 15) = 1

GCD of 40, 44, 15 is 1
