Given Input Data is 850, 780, 84, 505

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

Prime Factorization of 850 is 2 x 5 x 5 x 17

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 505 is 5 x 101

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(850, 780) = 66300

GCD(850, 780) = ( 850 x 780 ) / 66300

GCD(850, 780) = 663000 / 66300

GCD(850, 780) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 84

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

LCM(10, 84) = 420

GCD(10, 84) = ( 10 x 84 ) / 420

GCD(10, 84) = 840 / 420

GCD(10, 84) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 505

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

LCM(2, 505) = 1010

GCD(2, 505) = ( 2 x 505 ) / 1010

GCD(2, 505) = 1010 / 1010

GCD(2, 505) = 1

GCD of 850, 780, 84, 505 is 1
