Greatest Common Divisior

We found the divisors of 37, 40, 18 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 37, 40, 18 is 1.

Therefore, GCD of numbers 37, 40, 18 is 1

Given Input Data is 37, 40, 18

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

Prime Factorization of 37 is 37

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

Prime Factorization of 18 is 2 x 3 x 3

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(37, 40) = 1480

GCD(37, 40) = ( 37 x 40 ) / 1480

GCD(37, 40) = 1480 / 1480

GCD(37, 40) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 18

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

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

GCD(1, 18) = 18 / 18

GCD(1, 18) = 1

GCD of 37, 40, 18 is 1
