We found the divisors of 442, 133, 78, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 442, 133, 78, 605 is 1.

Therefore, GCD of numbers 442, 133, 78, 605 is 1

Given Input Data is 442, 133, 78, 605

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

Prime Factorization of 442 is 2 x 13 x 17

Prime Factorization of 133 is 7 x 19

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 605 is 5 x 11 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(442, 133) = 58786

GCD(442, 133) = ( 442 x 133 ) / 58786

GCD(442, 133) = 58786 / 58786

GCD(442, 133) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 78

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

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

GCD(1, 78) = 78 / 78

GCD(1, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 605

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

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

GCD(1, 605) = 605 / 605

GCD(1, 605) = 1

GCD of 442, 133, 78, 605 is 1
