Greatest Common Divisior

We found the divisors of 40, 73, 40 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 73, 40 is 1.

Therefore, GCD of numbers 40, 73, 40 is 1

Given Input Data is 40, 73, 40

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 73 is 73

Prime Factorization of 40 is 2 x 2 x 2 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, 73) = 2920

GCD(40, 73) = ( 40 x 73 ) / 2920

GCD(40, 73) = 2920 / 2920

GCD(40, 73) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 40

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

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

GCD(1, 40) = 40 / 40

GCD(1, 40) = 1

GCD of 40, 73, 40 is 1
