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

Apply this formula for all numbers.

Step1:

LCM(405, 723) = 97605

GCD(405, 723) = ( 405 x 723 ) / 97605

= 405 / 723

= 405

Step2:

LCM(3, 558) = 558

GCD(3, 558) = ( 3 x 558 ) / 558

= 3 / 558

= 3

So, Greatest Common Divisor of 405, 723, 558 is 3
