Therefore, GCD of numbers 816, 330, 66, 641 is 1

Given Input Data is 816, 330, 66, 641

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

Prime Factorization of 816 is 2 x 2 x 2 x 2 x 3 x 17

Prime Factorization of 330 is 2 x 3 x 5 x 11

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 641 is 641

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(816, 330) = 44880

GCD(816, 330) = ( 816 x 330 ) / 44880

GCD(816, 330) = 269280 / 44880

GCD(816, 330) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 66

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

LCM(6, 66) = 66

GCD(6, 66) = ( 6 x 66 ) / 66

GCD(6, 66) = 396 / 66

GCD(6, 66) = 6

Step3:

Here we consider the GCD from the above i.e. 6 as first number and the next as 641

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

LCM(6, 641) = 3846

GCD(6, 641) = ( 6 x 641 ) / 3846

GCD(6, 641) = 3846 / 3846

GCD(6, 641) = 1

GCD of 816, 330, 66, 641 is 1
