Three numbers.
1000
They are 500, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, and 5000.
64 is one possible answer.
Do a search on Google, for "prime numbers" table, or "prime numbers" list, and you will surely find something.I cannot tell precisely without looking up a table or doing some longish calculus but as a gross estimatation there should be about this many prime numbers between 1000 and 2000:2000 / ln(2000) - 1000 / ln(1000) =~ 263 - 144 = 119Actual number of primes between 1000 and 2000 should be a little above 119(in the range [140, 160] i think)

The multiples of 1,000 are an infinite number of integers in the set that begins 1000, 2000, 3000, 4000, and so on.
They are: 9/1000 itself and its equivalent fractions such as 18/2000
1000, 2000, 3000, 4000, 5000
500, 1000, 1500, 2000, 2500
They are: 500, 1000, 1500, 2000 . . .
500, 1000, 1500, 2000, 2500, 3000, 3500 . . .500, 1000, 1500, 2000, 2500, 3000, 3500 . . . to infinity.
All numbers that are divisible by 5 and 9 are multiples of their lcm which is 45. So the question boils down to which multiples of 45 are between 1000 & 2000. 1000 ÷ 45 = 222/9 2000 ÷ 45 = 444/9 Thus the solution is the multiples of 45 from 23 to 44 which are: 1035, 1080, 1125, 1170, 1215, 1260, 1305, 1350, 1395, 1440, 1485, 1530, 1575, 1620, 1665, 1710, 1755, 1800, 1845, 1890, 1935, 1980

Oh, isn't that a happy little question! Let's see here... To find the multiples of 10 between 2000 and 5000, we simply need to divide the endpoints by 10. When we do that, we get 200 and 500. So, there are 500 - 200 - 1 = 299 multiples of 10 between 2000 and 5000. Isn't that just delightful?
