We found the divisors of 634, 411, 85, 605 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 634, 411, 85, 605 is 1.

Therefore, GCD of numbers 634, 411, 85, 605 is 1

Given Input Data is 634, 411, 85, 605

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

Prime Factorization of 634 is 2 x 317

Prime Factorization of 411 is 3 x 137

Prime Factorization of 85 is 5 x 17

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(634, 411) = 260574

GCD(634, 411) = ( 634 x 411 ) / 260574

GCD(634, 411) = 260574 / 260574

GCD(634, 411) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 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 634, 411, 85, 605 is 1
