450 is one of 3 possible answers.

The greatest number between 450 and 500 that is divisible by six is 498.

There are many numbers between 500 and 1000 divisible by 3 and 9. Any number divisible by 9 is divisible by 3. How about 900?

To find out if a number is divisible by 3 add up all it's digest and check if the total is divisible by 3. to check if a number is divisible by 2 check if the last digit is divisible by 2. So one such number is 405.

this mean case numbers between 400 and 500 e.g. at the start of March: The key points you need to know from today is NPHET briefing

There are 67 numbers between 100 and 500 divisible by 6. The first number greater than 100 divisible by 6: 100 ÷ 6 = 16 r 4 → first number divisible by 6 is 6 × 17 = 102 Last number less than 500 divisible by 6: 500 ÷ 6 = 83 r 2 → last number divisible by 6 is 6 × 83 = 498 → all multiples of 6 between 17 × 6 and 83 × 6 inclusive are the numbers between 100 and 500 that are divisible by 6. → there are 83 - 17 + 1 = 67 such numbers.

Well, there is 16, 64, 144, above is answered by the first person... In this problem, the squared number must be a whole number and divisible by 4. 20^2 is 400. And there are 4, 8, 12, 16 ,20; 5 number divisible by 4. and 23^2 is already 529. the next number divisible by 4 is 24 which is over 500. So there are 5 numbers. They are 16, 64, 144, 256, 400.

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.

400 of them.
