Given Input Data is 280, 819, 74, 829

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 829 is 829

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(280, 819) = 32760

GCD(280, 819) = ( 280 x 819 ) / 32760

GCD(280, 819) = 229320 / 32760

GCD(280, 819) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 74

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

LCM(7, 74) = 518

GCD(7, 74) = ( 7 x 74 ) / 518

GCD(7, 74) = 518 / 518

GCD(7, 74) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 829

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

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

GCD(1, 829) = 829 / 829

GCD(1, 829) = 1

GCD of 280, 819, 74, 829 is 1
