Therefore, GCD of numbers 805, 301, 39, 321 is 1

Given Input Data is 805, 301, 39, 321

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

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 301 is 7 x 43

Prime Factorization of 39 is 3 x 13

Prime Factorization of 321 is 3 x 107

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(805, 301) = 34615

GCD(805, 301) = ( 805 x 301 ) / 34615

GCD(805, 301) = 242305 / 34615

GCD(805, 301) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 39

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

LCM(7, 39) = 273

GCD(7, 39) = ( 7 x 39 ) / 273

GCD(7, 39) = 273 / 273

GCD(7, 39) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 321

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

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

GCD(1, 321) = 321 / 321

GCD(1, 321) = 1

GCD of 805, 301, 39, 321 is 1
