Given numbers are 285, 261, 183, 863

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

Apply this formula for all numbers.

Step1:

LCM(285, 261) = 24795

GCD(285, 261) = ( 285 x 261 ) / 24795

= 285 / 261

= 285

Step2:

LCM(3, 183) = 183

GCD(3, 183) = ( 3 x 183 ) / 183

= 3 / 183

= 3

Step3:

LCM(3, 863) = 2589

GCD(3, 863) = ( 3 x 863 ) / 2589

= 3 / 863

= 3

So, Greatest Common Divisor of 285, 261, 183, 863 is 1
