Given Input Data is 843, 765, 573

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

Prime Factorization of 843 is 3 x 281

Prime Factorization of 765 is 3 x 3 x 5 x 17

Prime Factorization of 573 is 3 x 191

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(843, 765) = 214965

GCD(843, 765) = ( 843 x 765 ) / 214965

GCD(843, 765) = 644895 / 214965

GCD(843, 765) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 573

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

LCM(3, 573) = 573

GCD(3, 573) = ( 3 x 573 ) / 573

GCD(3, 573) = 1719 / 573

GCD(3, 573) = 3

GCD of 843, 765, 573 is 3
