How many children?
Math Professor Smith explained to one of his graduate students (Jones) that one day his children were playing in Smith's backyard with the children from 3 other families. Smith's family has the most children; the Browns have a smaller number of children; the Greene's have still a smaller number, and finally the White's have the smallest of all. "How many children are there altogether," asked Jones. "There are fewer than 18, and the product of the numbers in the four families happens to be my house number (which Jones already knew), said Smith. Jones began to scribble some numbers. A moment later he said he needed more info: "is there more than one child in the White family?" As soon as Smith replied, Jones knew the correct total of each family. The number of children in each family can now be solved however based solely on the info provided! ... Copied to Clipboard!

I must be missing something, but I don't think that's solvable with just that info? Not without knowing the answer to that question.
The question being asked provides the info that there exists multiple combinations that give the same product (the unknown to us house number). Asking if the smallest family is greater than 1 tells you that you can reach it with the smallest family at 1 or 2. The only overlap of products I can think of offhand that fit this are 2,3,4,5 and 1,4,5,6 which both yield a product of 120. Certainly hearing the answer to the presented question would eliminate one or the other but without hearing the answer ourselves... I don't think we can determine it? --- xp1337: Don't you wish there was a spell-checker that told you when you a word out? ... Copied to Clipboard!

Thats what I got!
The part about the product was a semi-red herring. Its not so much needing to know what the product is, its more so knowing that Jones was aware of an isolated number (that happened to be the product). ... Copied to Clipboard!

Yeah I was two seconds away from asking if we were supposed to know how many children Smith has or what his house number was.

Its very fascinating how some riddles seem so obviously unsolvable until you delve into them. For me, this was one of them.
