To divide 4000 evenly, the number of giveaways depends on how many items each giveaway should get. The math is:

4000÷number of giveaways=amount per giveaway4000\div \text{number of giveaways}=\text{amount per giveaway}4000÷number of giveaways=amount per giveaway

Examples:

  • 2 giveaways = 2000 each
  • 4 giveaways = 1000 each
  • 10 giveaways = 400 each
  • 100 giveaways = 40 each

If you mean how many giveaways are needed for 4000 total items , then the answer is simply the number of groups you want to split them into. For an even split, use:

giveaways=4000÷items per giveaway\text{giveaways}=4000\div \text{items per giveaway}giveaways=4000÷items per giveaway

A prize-splitting calculator describes the same idea: divide the total amount by the number of recipients to get each share.
