Given Input Data is 156, 447, 33, 731

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

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 447 is 3 x 149

Prime Factorization of 33 is 3 x 11

Prime Factorization of 731 is 17 x 43

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(156, 447) = 23244

GCD(156, 447) = ( 156 x 447 ) / 23244

GCD(156, 447) = 69732 / 23244

GCD(156, 447) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 33

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

LCM(3, 33) = 33

GCD(3, 33) = ( 3 x 33 ) / 33

GCD(3, 33) = 99 / 33

GCD(3, 33) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 731

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

LCM(3, 731) = 2193

GCD(3, 731) = ( 3 x 731 ) / 2193

GCD(3, 731) = 2193 / 2193

GCD(3, 731) = 1

GCD of 156, 447, 33, 731 is 1
