Therefore, GCD of numbers 385, 415, 330, 787 is 1

Given Input Data is 385, 415, 330, 787

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 415 is 5 x 83

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

Prime Factorization of 787 is 787

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(385, 415) = 31955

GCD(385, 415) = ( 385 x 415 ) / 31955

GCD(385, 415) = 159775 / 31955

GCD(385, 415) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 330

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

LCM(5, 330) = 330

GCD(5, 330) = ( 5 x 330 ) / 330

GCD(5, 330) = 1650 / 330

GCD(5, 330) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 787

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

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

GCD(5, 787) = 3935 / 3935

GCD(5, 787) = 1

GCD of 385, 415, 330, 787 is 1
