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

Apply this formula for all numbers.

Step1:

LCM(405, 295) = 23895

GCD(405, 295) = ( 405 x 295 ) / 23895

= 405 / 295

= 405

Step2:

LCM(5, 285) = 285

GCD(5, 285) = ( 5 x 285 ) / 285

= 5 / 285

= 5

So, Greatest Common Divisor of 405, 295, 285 is 5
