Greatest Common Divisior

We found the divisors of 83, 15, 31 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 83, 15, 31 is 1.

Therefore, GCD of numbers 83, 15, 31 is 1

Given Input Data is 83, 15, 31

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

Prime Factorization of 83 is 83

Prime Factorization of 15 is 3 x 5

Prime Factorization of 31 is 31

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(83, 15) = 1245

GCD(83, 15) = ( 83 x 15 ) / 1245

GCD(83, 15) = 1245 / 1245

GCD(83, 15) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 31

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

LCM(1, 31) = 31

GCD(1, 31) = ( 1 x 31 ) / 31

GCD(1, 31) = 31 / 31

GCD(1, 31) = 1

GCD of 83, 15, 31 is 1
