The answer is 150 which is greater than 30, we must include the case when and (since the question doesn't explicitly ask us to use only non-trivial divisors). A justification of the above statement is as follows:
The set of all possible values for the product ab is . Now suppose the smallest value that ab must be a factor of were less than 150, take for instance that it was 75, then if , we'd have the contradiction that 150 is not a factor of 75. We can extend this line of reasoning to any other number . Thus the only number that satisfies the requirements is 150.

In August 2013, E*TRADE Financial was offering only 0.05% interest on its online checking accounts, with interest reinvested monthly. Find the associated exponential model for the value of a $5000 deposit after "t" years. Assuming that this rate of return continued for 7 years, how much would a deposit of $5000 in August 2013 be worth in August 2020? (Answer to the nearest $1. )
