We found the divisors of 127, 317, 132, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 127, 317, 132, 645 is 1.

Therefore, GCD of numbers 127, 317, 132, 645 is 1

Given Input Data is 127, 317, 132, 645

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

Prime Factorization of 127 is 127

Prime Factorization of 317 is 317

Prime Factorization of 132 is 2 x 2 x 3 x 11

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(127, 317) = 40259

GCD(127, 317) = ( 127 x 317 ) / 40259

GCD(127, 317) = 40259 / 40259

GCD(127, 317) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 132

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

LCM(1, 132) = 132

GCD(1, 132) = ( 1 x 132 ) / 132

GCD(1, 132) = 132 / 132

GCD(1, 132) = 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 127, 317, 132, 645 is 1
