Given numbers are 843, 648, 993, 285

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

Apply this formula for all numbers.

Step1:

LCM(843, 648) = 182088

GCD(843, 648) = ( 843 x 648 ) / 182088

= 843 / 648

= 843

Step2:

LCM(3, 993) = 993

GCD(3, 993) = ( 3 x 993 ) / 993

= 3 / 993

= 3

Step3:

LCM(3, 285) = 285

GCD(3, 285) = ( 3 x 285 ) / 285

= 3 / 285

= 3

So, Greatest Common Divisor of 843, 648, 993, 285 is 3
