Greatest Common Divisior

We found the divisors of 66, 9, 13, 59 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 66, 9, 13, 59 is 1.

Therefore, GCD of numbers 66, 9, 13, 59 is 1

Given Input Data is 66, 9, 13, 59

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 9 is 3 x 3

Prime Factorization of 13 is 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(66, 9) = 198

GCD(66, 9) = ( 66 x 9 ) / 198

GCD(66, 9) = 594 / 198

GCD(66, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 13

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

LCM(3, 13) = 39

GCD(3, 13) = ( 3 x 13 ) / 39

GCD(3, 13) = 39 / 39

GCD(3, 13) = 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 66, 9, 13, 59 is 1
