Therefore, GCD of numbers 133, 154, 81, 330 is 1

Given Input Data is 133, 154, 81, 330

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

Prime Factorization of 133 is 7 x 19

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 330 is 2 x 3 x 5 x 11

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, 154) = 2926

GCD(133, 154) = ( 133 x 154 ) / 2926

GCD(133, 154) = 20482 / 2926

GCD(133, 154) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 81

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

LCM(7, 81) = 567

GCD(7, 81) = ( 7 x 81 ) / 567

GCD(7, 81) = 567 / 567

GCD(7, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 330

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

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

GCD(1, 330) = 330 / 330

GCD(1, 330) = 1

GCD of 133, 154, 81, 330 is 1
