We found the divisors of 995, 174, 107, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 995, 174, 107, 645 is 1.

Therefore, GCD of numbers 995, 174, 107, 645 is 1

Given Input Data is 995, 174, 107, 645

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

Prime Factorization of 995 is 5 x 199

Prime Factorization of 174 is 2 x 3 x 29

Prime Factorization of 107 is 107

Prime Factorization of 645 is 3 x 5 x 43

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(995, 174) = 173130

GCD(995, 174) = ( 995 x 174 ) / 173130

GCD(995, 174) = 173130 / 173130

GCD(995, 174) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 107

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

LCM(1, 107) = 107

GCD(1, 107) = ( 1 x 107 ) / 107

GCD(1, 107) = 107 / 107

GCD(1, 107) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

GCD of 995, 174, 107, 645 is 1
