Given Input Data is 681, 225, 543

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

Prime Factorization of 681 is 3 x 227

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 543 is 3 x 181

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(681, 225) = 51075

GCD(681, 225) = ( 681 x 225 ) / 51075

GCD(681, 225) = 153225 / 51075

GCD(681, 225) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 543

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

LCM(3, 543) = 543

GCD(3, 543) = ( 3 x 543 ) / 543

GCD(3, 543) = 1629 / 543

GCD(3, 543) = 3

GCD of 681, 225, 543 is 3
