Therefore, GCD of numbers 225, 909, 86, 663 is 1

Given Input Data is 225, 909, 86, 663

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

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

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 86 is 2 x 43

Prime Factorization of 663 is 3 x 13 x 17

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(225, 909) = 22725

GCD(225, 909) = ( 225 x 909 ) / 22725

GCD(225, 909) = 204525 / 22725

GCD(225, 909) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 86

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

LCM(9, 86) = 774

GCD(9, 86) = ( 9 x 86 ) / 774

GCD(9, 86) = 774 / 774

GCD(9, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 663

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

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

GCD(1, 663) = 663 / 663

GCD(1, 663) = 1

GCD of 225, 909, 86, 663 is 1
