Math facts about 15
15 is composite because the factors of 15 are 1,3,5, and 15. Composite Numbers have more than two factors.
The number 15 is also odd because 15/2=7.5.
15 is deficient because it’s proper factors are 1,3, and 5. 1+3+5=9. 9 is less than 15 so 15 is deficient.
World facts about 15
In the game, baseball, my favorite team, the Giants, have Noah Lowry(the pitcher.) His number is 51and that transposed=15.
Behind my condo, I can see 15 lights from the construction site.
The multiples of 15 are basic clock numbers. 15 minutes = a quarter of an hour.
Factor Game
For the factor game, my number would be an OK 1st move because the proper factors are 1,3, and 5. So 1+3+5=9. Your opponent would get 9 and you would get 15. You would still get more than your opponent, but it is not very much more.
Product Game
My number would not be a very good result for the product game because 15 is out on the left side so it is hard to get 4 products in a row with the numbers surrounding it.
