Given Input Data is 543, 858, 657

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

Prime Factorization of 543 is 3 x 181

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

Prime Factorization of 657 is 3 x 3 x 73

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(543, 858) = 155298

GCD(543, 858) = ( 543 x 858 ) / 155298

GCD(543, 858) = 465894 / 155298

GCD(543, 858) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 657

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

LCM(3, 657) = 657

GCD(3, 657) = ( 3 x 657 ) / 657

GCD(3, 657) = 1971 / 657

GCD(3, 657) = 3

GCD of 543, 858, 657 is 3
