Greatest Common Divisior

We found the divisors of 38, 40, 53 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 38, 40, 53 is 1.

Therefore, GCD of numbers 38, 40, 53 is 1

Given Input Data is 38, 40, 53

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

Prime Factorization of 38 is 2 x 19

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

Prime Factorization of 53 is 53

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(38, 40) = 760

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

GCD(38, 40) = 1520 / 760

GCD(38, 40) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 53

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

LCM(2, 53) = 106

GCD(2, 53) = ( 2 x 53 ) / 106

GCD(2, 53) = 106 / 106

GCD(2, 53) = 1

GCD of 38, 40, 53 is 1
