We found the divisors of 40, 38, 99 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 38, 99 is 1.

Therefore, GCD of numbers 40, 38, 99 is 1

Given Input Data is 40, 38, 99

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 38 is 2 x 19

Prime Factorization of 99 is 3 x 3 x 11

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, 38) = 760

GCD(40, 38) = ( 40 x 38 ) / 760

GCD(40, 38) = 1520 / 760

GCD(40, 38) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 99

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

LCM(2, 99) = 198

GCD(2, 99) = ( 2 x 99 ) / 198

GCD(2, 99) = 198 / 198

GCD(2, 99) = 1

GCD of 40, 38, 99 is 1
