Given Input Data is 405, 655, 587, 456

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 655 is 5 x 131

Prime Factorization of 587 is 587

Prime Factorization of 456 is 2 x 2 x 2 x 3 x 19

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, 655) = 53055

GCD(405, 655) = ( 405 x 655 ) / 53055

GCD(405, 655) = 265275 / 53055

GCD(405, 655) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 587

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

LCM(5, 587) = 2935

GCD(5, 587) = ( 5 x 587 ) / 2935

GCD(5, 587) = 2935 / 2935

GCD(5, 587) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 456

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

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

GCD(1, 456) = 456 / 456

GCD(1, 456) = 1

GCD of 405, 655, 587, 456 is 1
