Given numbers are 447, 306, 789, 340

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

Apply this formula for all numbers.

Step1:

LCM(447, 306) = 45594

GCD(447, 306) = ( 447 x 306 ) / 45594

= 447 / 306

= 447

Step2:

LCM(3, 789) = 789

GCD(3, 789) = ( 3 x 789 ) / 789

= 3 / 789

= 3

Step3:

LCM(3, 340) = 1020

GCD(3, 340) = ( 3 x 340 ) / 1020

= 3 / 340

= 3

So, Greatest Common Divisor of 447, 306, 789, 340 is 1
