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

Apply this formula for all numbers.

Step1:

LCM(405, 755) = 61155

GCD(405, 755) = ( 405 x 755 ) / 61155

= 405 / 755

= 405

Step2:

LCM(5, 395) = 395

GCD(5, 395) = ( 5 x 395 ) / 395

= 5 / 395

= 5

Step3:

LCM(5, 255) = 255

GCD(5, 255) = ( 5 x 255 ) / 255

= 5 / 255

= 5

So, Greatest Common Divisor of 405, 755, 395, 255 is 5
