Given numbers are 290, 590, 405

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

Apply this formula for all numbers.

Step1:

LCM(290, 590) = 17110

GCD(290, 590) = ( 290 x 590 ) / 17110

= 290 / 590

= 290

Step2:

LCM(10, 405) = 810

GCD(10, 405) = ( 10 x 405 ) / 810

= 10 / 405

= 10

So, Greatest Common Divisor of 290, 590, 405 is 5
