Greatest Common Divisior

We found the divisors of 80, 9, 91, 59 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 9, 91, 59 is 1.

Therefore, GCD of numbers 80, 9, 91, 59 is 1

Given Input Data is 80, 9, 91, 59

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 9 is 3 x 3

Prime Factorization of 91 is 7 x 13

Prime Factorization of 59 is 59

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, 9) = 720

GCD(80, 9) = ( 80 x 9 ) / 720

GCD(80, 9) = 720 / 720

GCD(80, 9) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 59

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

LCM(1, 59) = 59

GCD(1, 59) = ( 1 x 59 ) / 59

GCD(1, 59) = 59 / 59

GCD(1, 59) = 1

GCD of 80, 9, 91, 59 is 1
