What are 2 consecutive positive integers whose product is 1332?

Answer 1

I would start by taking the square root of 1332, which is 36.4966, then try 36 x 37, which works. If you don't have a calculator handy to do square roots, then note that 1332 is between 900 (a perfect square 30^2) and 1600 (a perfect square 40^2). Then just start with consecutive numbers in that range. It's a little closer to 1600, so you could start with 35 times 36 and see what that is, then try another, till you get the answer.
