Given Input Data is 819, 923, 818, 165

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

Prime Factorization of 819 is 3 x 3 x 7 x 13

Prime Factorization of 923 is 13 x 71

Prime Factorization of 818 is 2 x 409

Prime Factorization of 165 is 3 x 5 x 11

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(819, 923) = 58149

GCD(819, 923) = ( 819 x 923 ) / 58149

GCD(819, 923) = 755937 / 58149

GCD(819, 923) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 818

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

LCM(13, 818) = 10634

GCD(13, 818) = ( 13 x 818 ) / 10634

GCD(13, 818) = 10634 / 10634

GCD(13, 818) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 165

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

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

GCD(1, 165) = 165 / 165

GCD(1, 165) = 1

GCD of 819, 923, 818, 165 is 1
