Greatest Common Divisior

We found the divisors of 80, 45, 73 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 45, 73 is 1.

Therefore, GCD of numbers 80, 45, 73 is 1

Given Input Data is 80, 45, 73

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 73 is 73

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(80, 45) = 720

GCD(80, 45) = ( 80 x 45 ) / 720

GCD(80, 45) = 3600 / 720

GCD(80, 45) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 73

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

LCM(5, 73) = 365

GCD(5, 73) = ( 5 x 73 ) / 365

GCD(5, 73) = 365 / 365

GCD(5, 73) = 1

GCD of 80, 45, 73 is 1
