9 4 4 3 2
I would make a guess at 2 to the power (3 to the power (4 to the power (4 to the power 9))) but I haven't checked it.
the largest five digit number that can be formed using the digits 7 and 9 is 97,000
99,997
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.
98765
With repetition, the smallest is 22222 and the largest is 88888 Without repetition, the smallest is 23458 and the largest is 85432

99874To solve this type of problems, you go from left to right, using the largest possible digit in every case.
The only number that ONLY has two and five as factors is 10, which has two digits, so there are no numbers that are three digits long and ONLY have two and five for factors. However, if you are asking what the largest three digit number that has two and five for factors, it would be the largest three digit number with ten as a factor, as ten the the LCM of two and five, and that would be 390.
The largest 5-digit number divisible exactly by 99 is 99990.
The largest five-digit whole number is 99,999. It is composed of five digits, all of which are nines, representing the highest value possible in that digit range. Any number greater than this would move into the six-digit category.
99997
Five digits.
94205 if digits are not to be repeated and 99999 if digits can be repeated
