Given numbers are 168, 405, 801, 509

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 801 are 3 x 3 x 89

Prime factors of 509 are 509

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 168, 405, 801, 509

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(168, 405) = 22680

GCD(168, 405) = ( 168 x 405 ) / 22680

= 168 / 405

= 168

Step2:

LCM(3, 801) = 801

GCD(3, 801) = ( 3 x 801 ) / 801

= 3 / 801

= 3

Step3:

LCM(3, 509) = 1527

GCD(3, 509) = ( 3 x 509 ) / 1527

= 3 / 509

= 3

So, Greatest Common Divisor of 168, 405, 801, 509 is 1
