We found the divisors of 31, 39, 83 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 31, 39, 83 is 1.

Therefore, GCD of numbers 31, 39, 83 is 1

Given Input Data is 31, 39, 83

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

Prime Factorization of 31 is 31

Prime Factorization of 39 is 3 x 13

Prime Factorization of 83 is 83

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(31, 39) = 1209

GCD(31, 39) = ( 31 x 39 ) / 1209

GCD(31, 39) = 1209 / 1209

GCD(31, 39) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 83

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

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

GCD(1, 83) = 83 / 83

GCD(1, 83) = 1

GCD of 31, 39, 83 is 1
