Given numbers are 585, 129, 234, 621

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

Apply this formula for all numbers.

Step1:

LCM(585, 129) = 25155

GCD(585, 129) = ( 585 x 129 ) / 25155

= 585 / 129

= 585

Step2:

LCM(3, 234) = 234

GCD(3, 234) = ( 3 x 234 ) / 234

= 3 / 234

= 3

Step3:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

So, Greatest Common Divisor of 585, 129, 234, 621 is 3
