[12:38 PM EST - Mental Exercise: Number seven.]

I got a set of Mensa logic puzzles for Christmas from the guys at work. I've been going through them fairly slowly. I've been stuck on one for a while. (I went ahead and tried a bunch afterward and they were easier.) I'll let you guys try it for yourselves.

Fill in the missing numbers from these bars. Just enough information has been provided to work out the logic. The logic is the same in each line of numbers.

74882, 3584, ?
29637, ?, 192
74826, ?, ?

Any suggestions?

74882, 3584, 480

29637, 2268, 192

74826, 2688, 768

I worked these out a couple of years ago but for the life of me, I cannot recall the logic I used.

Correct! The values are obtained by multiplying the digits to the left of the number. e.g. 7 x 4 x 8 x 8 x 2 = 3584.
