Given Input Data is 666, 225, 40

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

Prime Factorization of 666 is 2 x 3 x 3 x 37

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

Prime Factorization of 40 is 2 x 2 x 2 x 5

The above numbers do not have any common prime factor. So GCD is 1

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(666, 225) = 16650

GCD(666, 225) = ( 666 x 225 ) / 16650

GCD(666, 225) = 149850 / 16650

GCD(666, 225) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 40

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

LCM(9, 40) = 360

GCD(9, 40) = ( 9 x 40 ) / 360

GCD(9, 40) = 360 / 360

GCD(9, 40) = 1

GCD of 666, 225, 40 is 1
