There are (500-100)/2 = 200 numbers divisible by 2 between 100 and 500 counting 100 but not 500. Of these (500-100)/8 = 50 are divisible by 8. So there are 150 numbers between 100 and 500 divisible by two but not by 8. By relative primeness exactly 50 out of these 150 are divisible by 3 and therefore these 50 are exactly the ones divisible by 6 but not by 8.

Assuming the question is the wrong way round, and meant to read 'between 400 and 500', then 441 = 21 x 21 484 = 22 x 22 as there are many under 400 and an infinite number over 500.

It is closer to 400 because 5 and over are always going up to the next number in rounding. For example, if it was 453, it would round up to 500. But it is 432 so its 400.

437 to the nearest hundred is 400.
