Given Input Data is 231, 858, 121

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

Prime Factorization of 231 is 3 x 7 x 11

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

Prime Factorization of 121 is 11 x 11

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(231, 858) = 6006

GCD(231, 858) = ( 231 x 858 ) / 6006

GCD(231, 858) = 198198 / 6006

GCD(231, 858) = 33

Step2:

Here we consider the GCD from the above i.e. 33 as first number and the next as 121

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

LCM(33, 121) = 363

GCD(33, 121) = ( 33 x 121 ) / 363

GCD(33, 121) = 3993 / 363

GCD(33, 121) = 11

GCD of 231, 858, 121 is 11
