Given numbers are 405, 810, 190, 870

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

Apply this formula for all numbers.

Step1:

LCM(405, 810) = 810

GCD(405, 810) = ( 405 x 810 ) / 810

= 405 / 810

= 405

Step2:

LCM(405, 190) = 15390

GCD(405, 190) = ( 405 x 190 ) / 15390

= 405 / 190

= 405

Step3:

LCM(5, 870) = 870

GCD(5, 870) = ( 5 x 870 ) / 870

= 5 / 870

= 5

So, Greatest Common Divisor of 405, 810, 190, 870 is 5
