Given Input Data is 156, 663, 403, 501

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 663 is 3 x 13 x 17

Prime Factorization of 403 is 13 x 31

Prime Factorization of 501 is 3 x 167

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, 663) = 2652

GCD(156, 663) = ( 156 x 663 ) / 2652

GCD(156, 663) = 103428 / 2652

GCD(156, 663) = 39

Step2:

Here we consider the GCD from the above i.e. 39 as first number and the next as 403

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

LCM(39, 403) = 1209

GCD(39, 403) = ( 39 x 403 ) / 1209

GCD(39, 403) = 15717 / 1209

GCD(39, 403) = 13

Step3:

Here we consider the GCD from the above i.e. 13 as first number and the next as 501

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

LCM(13, 501) = 6513

GCD(13, 501) = ( 13 x 501 ) / 6513

GCD(13, 501) = 6513 / 6513

GCD(13, 501) = 1

GCD of 156, 663, 403, 501 is 1
