Greatest Common Divisior

We found the divisors of 31, 42, 29 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 31, 42, 29 is 1.

Therefore, GCD of numbers 31, 42, 29 is 1

Given Input Data is 31, 42, 29

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

Prime Factorization of 31 is 31

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 29 is 29

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, 42) = 1302

GCD(31, 42) = ( 31 x 42 ) / 1302

GCD(31, 42) = 1302 / 1302

GCD(31, 42) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 29

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

LCM(1, 29) = 29

GCD(1, 29) = ( 1 x 29 ) / 29

GCD(1, 29) = 29 / 29

GCD(1, 29) = 1

GCD of 31, 42, 29 is 1
