The largest 5-digit number divisible exactly by 99 is 99990.
99990 ----------------------------------------------------------------------------------------------- Largest 5 digit number is 99999 99999 ÷ 99 = 1010 r 9 → largest 5 digit number divisible by 99 is 99 x 1010 = 99990
A five-digit number that is divisible by both 9 and 4 must meet the criteria for divisibility by these numbers. A number is divisible by 9 if the sum of its digits is divisible by 9, and it is divisible by 4 if the last two digits form a number that is divisible by 4. The smallest five-digit number is 10,000, and the largest is 99,999; thus, any five-digit number that meets these criteria can be calculated by finding the least common multiple of 9 and 4, which is 36, and checking multiples of 36 within that range. For example, 10,008 is a five-digit number divisible by both 9 and 4.

To determine if a number is divisible by 96, it must be divisible by both 32 and 3, since 96 = 32 × 3. For divisibility by 32, the last five digits of the number must be divisible by 32. For divisibility by 3, the sum of the digits of the number must be divisible by 3. If both conditions are met, then the number is divisible by 96.

the largest five digit number that can be formed using the digits 7 and 9 is 97,000
To be divisible by 15, it must also be divisible by 3 and by 5. To be divisible by 3, the sum of the digits must be divisible by 3; to be divisible by 5, the number must end with a zero or a five. Considering all these criteria, I guess that number would be 1110.
97632 is the largest number containing these digits. To make the largest number simply order the numbers in descending order. As it happens this results in an even number so nothing further is necessary.
I suggest you try getting different multiples of 41,000, until you find one that has five digits.
