ANSWER:The numbers that are divisible by 9 are the numbers whose sum of the digits is a multiple of 9Example:27 = 2 + 7 = 9 (9 is a multiple of 9 thus 27 is divisible by 9)99 = 9 + 9 = 18 (18 is a multiple of 9 thus 99 is divisible by 9)

The least common multiple of the numbers 4, 27 and 9 is 108.

288. All multiples of 9 will have digits that add to a multiple of 9. To get a multiple of 9 to be all even, you need to get them to add to 18, since no set of even numbers will add up to 9. 288 is the lowest multiple of 9 to be able to add to 18. ■

No. Numbers divisible by 9 have digits that add up to a multiple of 9. 2+3+6=11, which is not a multiple of 9.

The least common multiple of the numbers 22, 9 and 44 is 396.
