99 of them.
There are infinitely many common multiples. One example is 31920.
60 and the infinitely many multiples of 60.
There are 10 multiples of 6 in that range.
The common multiples of 142 and 148 are 10,508, 21,016, 31,524, and so on.
I would do it like this though I'm sure there are other ways: There are 10 multiples of 3 every 30 (3,6,9,12,15,18,21,24,27,30). There are (1000/30)= 33 lots of 30 in 1000 Therefore there are (10 x 33)=330 multiples of 3 which brings us up to 990 (330x3 =990) Then there are 3 more multiples of 3 993, 996,999 This makes the total 333 multiples of three between 1 and 1001

The last "x7" under 100 is 14 x 7, the last under 1000 is 142 x 7, so there are 128 in the range.
There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.
500
floor(1000/8)=125
333
Only the multiples of 1000.
Oh, dude, multiples of 4 are like those friends who always show up at your party. They just keep coming. So, to find out how many multiples of 4 are up to 1000, you just divide 1000 by 4, which gives you 250. So, there are 250 multiples of 4 up to 1000. It's like a never-ending party!
110.
Ten of them.
