Given Input Data is 909, 216, 855, 451

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

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 451 is 11 x 41

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(909, 216) = 21816

GCD(909, 216) = ( 909 x 216 ) / 21816

GCD(909, 216) = 196344 / 21816

GCD(909, 216) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 855

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

LCM(9, 855) = 855

GCD(9, 855) = ( 9 x 855 ) / 855

GCD(9, 855) = 7695 / 855

GCD(9, 855) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 451

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

LCM(9, 451) = 4059

GCD(9, 451) = ( 9 x 451 ) / 4059

GCD(9, 451) = 4059 / 4059

GCD(9, 451) = 1

GCD of 909, 216, 855, 451 is 1
