Given numbers are 288, 819, 309, 831

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

Apply this formula for all numbers.

Step1:

LCM(288, 819) = 26208

GCD(288, 819) = ( 288 x 819 ) / 26208

= 288 / 819

= 288

Step2:

LCM(9, 309) = 927

GCD(9, 309) = ( 9 x 309 ) / 927

= 9 / 309

= 9

Step3:

LCM(3, 831) = 831

GCD(3, 831) = ( 3 x 831 ) / 831

= 3 / 831

= 3

So, Greatest Common Divisor of 288, 819, 309, 831 is 3
