Therefore, GCD of numbers 304, 855, 77, 353 is 1

Given Input Data is 304, 855, 77, 353

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

Prime Factorization of 304 is 2 x 2 x 2 x 2 x 19

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 77 is 7 x 11

Prime Factorization of 353 is 353

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(304, 855) = 13680

GCD(304, 855) = ( 304 x 855 ) / 13680

GCD(304, 855) = 259920 / 13680

GCD(304, 855) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 77

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

LCM(19, 77) = 1463

GCD(19, 77) = ( 19 x 77 ) / 1463

GCD(19, 77) = 1463 / 1463

GCD(19, 77) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 353

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

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

GCD(1, 353) = 353 / 353

GCD(1, 353) = 1

GCD of 304, 855, 77, 353 is 1
