Given Input Data is 781, 858, 517

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 517 is 11 x 47

Highest common occurrences in the given inputs are 11¹

Multiplying them we get the GCD as 11

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(781, 858) = 60918

GCD(781, 858) = ( 781 x 858 ) / 60918

GCD(781, 858) = 670098 / 60918

GCD(781, 858) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 517

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

LCM(11, 517) = 517

GCD(11, 517) = ( 11 x 517 ) / 517

GCD(11, 517) = 5687 / 517

GCD(11, 517) = 11

GCD of 781, 858, 517 is 11
