We found the divisors of 93, 9, 68, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 93, 9, 68, 20 is 1.

Therefore, GCD of numbers 93, 9, 68, 20 is 1

Given Input Data is 93, 9, 68, 20

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

Prime Factorization of 93 is 3 x 31

Prime Factorization of 9 is 3 x 3

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 20 is 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(93, 9) = 279

GCD(93, 9) = ( 93 x 9 ) / 279

GCD(93, 9) = 837 / 279

GCD(93, 9) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 68

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

LCM(3, 68) = 204

GCD(3, 68) = ( 3 x 68 ) / 204

GCD(3, 68) = 204 / 204

GCD(3, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 93, 9, 68, 20 is 1
