Given numbers are 218, 284, 609, 809

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

Apply this formula for all numbers.

Step1:

LCM(218, 284) = 30956

GCD(218, 284) = ( 218 x 284 ) / 30956

= 218 / 284

= 218

Step2:

LCM(2, 609) = 1218

GCD(2, 609) = ( 2 x 609 ) / 1218

= 2 / 609

= 2

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 218, 284, 609, 809 is 1
