Given Input Data is 405, 933, 655, 900

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 933 is 3 x 311

Prime Factorization of 655 is 5 x 131

Prime Factorization of 900 is 2 x 2 x 3 x 3 x 5 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(405, 933) = 125955

GCD(405, 933) = ( 405 x 933 ) / 125955

GCD(405, 933) = 377865 / 125955

GCD(405, 933) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 655

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

LCM(3, 655) = 1965

GCD(3, 655) = ( 3 x 655 ) / 1965

GCD(3, 655) = 1965 / 1965

GCD(3, 655) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 900

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

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

GCD(1, 900) = 900 / 900

GCD(1, 900) = 1

GCD of 405, 933, 655, 900 is 1
