Therefore, GCD of numbers 133, 903, 76, 243 is 1

Given Input Data is 133, 903, 76, 243

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

Prime Factorization of 133 is 7 x 19

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

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(133, 903) = 17157

GCD(133, 903) = ( 133 x 903 ) / 17157

GCD(133, 903) = 120099 / 17157

GCD(133, 903) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 76

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

LCM(7, 76) = 532

GCD(7, 76) = ( 7 x 76 ) / 532

GCD(7, 76) = 532 / 532

GCD(7, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 243

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

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

GCD(1, 243) = 243 / 243

GCD(1, 243) = 1

GCD of 133, 903, 76, 243 is 1
