Therefore, GCD of numbers 322, 777, 849, 245 is 1

Given Input Data is 322, 777, 849, 245

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

Prime Factorization of 322 is 2 x 7 x 23

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 849 is 3 x 283

Prime Factorization of 245 is 5 x 7 x 7

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(322, 777) = 35742

GCD(322, 777) = ( 322 x 777 ) / 35742

GCD(322, 777) = 250194 / 35742

GCD(322, 777) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 849

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

LCM(7, 849) = 5943

GCD(7, 849) = ( 7 x 849 ) / 5943

GCD(7, 849) = 5943 / 5943

GCD(7, 849) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 322, 777, 849, 245 is 1
