We found the divisors of 405, 185, 806, 507 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 405, 185, 806, 507 is 1.

Therefore, GCD of numbers 405, 185, 806, 507 is 1

Given Input Data is 405, 185, 806, 507

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

Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5

Prime Factorization of 185 is 5 x 37

Prime Factorization of 806 is 2 x 13 x 31

Prime Factorization of 507 is 3 x 13 x 13

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(405, 185) = 14985

GCD(405, 185) = ( 405 x 185 ) / 14985

GCD(405, 185) = 74925 / 14985

GCD(405, 185) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 806

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

LCM(5, 806) = 4030

GCD(5, 806) = ( 5 x 806 ) / 4030

GCD(5, 806) = 4030 / 4030

GCD(5, 806) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 507

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

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

GCD(1, 507) = 507 / 507

GCD(1, 507) = 1

GCD of 405, 185, 806, 507 is 1
