We found the divisors of 39, 91, 99, 59 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 39, 91, 99, 59 is 1.

Therefore, GCD of numbers 39, 91, 99, 59 is 1

Given Input Data is 39, 91, 99, 59

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

Prime Factorization of 39 is 3 x 13

Prime Factorization of 91 is 7 x 13

Prime Factorization of 99 is 3 x 3 x 11

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(39, 91) = 273

GCD(39, 91) = ( 39 x 91 ) / 273

GCD(39, 91) = 3549 / 273

GCD(39, 91) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 99

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

LCM(13, 99) = 1287

GCD(13, 99) = ( 13 x 99 ) / 1287

GCD(13, 99) = 1287 / 1287

GCD(13, 99) = 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 39, 91, 99, 59 is 1
