Given Input Data is 822, 570, 53, 868

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

Prime Factorization of 822 is 2 x 3 x 137

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 53 is 53

Prime Factorization of 868 is 2 x 2 x 7 x 31

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(822, 570) = 78090

GCD(822, 570) = ( 822 x 570 ) / 78090

GCD(822, 570) = 468540 / 78090

GCD(822, 570) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 53

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

LCM(6, 53) = 318

GCD(6, 53) = ( 6 x 53 ) / 318

GCD(6, 53) = 318 / 318

GCD(6, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 868

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

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

GCD(1, 868) = 868 / 868

GCD(1, 868) = 1

GCD of 822, 570, 53, 868 is 1
