The numbers divisible by both 3 and 4 are multiples of 12, thus between 10 and 99: 12, 24, 36, 48, 60, 72, 84, 96 are the numbers divisible by both 3 and 4.
A number divisible by 99 is any integer that can be expressed as (99n), where (n) is an integer. For example, 198 (which is (99 \times 2)) and 297 (which is (99 \times 3)) are both divisible by 99. The key characteristic of these numbers is that they must meet the divisibility rule for both 9 and 11, since 99 is the product of these two primes.
