Therefore, GCD of numbers 793, 182, 645 is 1

Given Input Data is 793, 182, 645

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

Prime Factorization of 793 is 13 x 61

Prime Factorization of 182 is 2 x 7 x 13

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(793, 182) = 11102

GCD(793, 182) = ( 793 x 182 ) / 11102

GCD(793, 182) = 144326 / 11102

GCD(793, 182) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 645

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

LCM(13, 645) = 8385

GCD(13, 645) = ( 13 x 645 ) / 8385

GCD(13, 645) = 8385 / 8385

GCD(13, 645) = 1

GCD of 793, 182, 645 is 1
