I'm in 7th grade trying to take a pre-algebra class..... we just learned our rules but i have come to the conclusion of 133.
Total number of 3 digit numbers = 999-100+1(to include 100)= 900 numbers
Therefore numbers not divisble by 2,3,5 and 10 are
900*(1-1/2)*(1-1/3)*(1-1/4)*(1-1/5)*(1-1/10)= 216 numbers

What are all the positive integers divisible by 2 or 3?
Well, darling, the positive integers divisible by 2 are all the even numbers, and the ones divisible by 3 are those multiples of 3. So, to find the numbers divisible by either 2 or 3, you just need to combine these two sets. In other words, it's the set of all even numbers and multiples of 3. Voilà!
How do you know if a number divisible by 3?
Add together all the digits until you get a single figure answer. If that's divisible by three, so's the original number. E.g. 4,239 broken down to 4 + 2 + 3 + 9 = 18; 1 + 8 = 9, which is a multiple of 3. The original number is therefore divisible by 3
What numbers is divisible by 255 2 3 4 5 6 7 8 9 or 10?
Out of that list, 255 is evenly divisible by 3 and 5.
Is 4908 divisible by 3?
To determine if 4908 is divisible by 3, we need to sum its digits. 4 + 9 + 0 + 8 = 21. Since 21 is divisible by 3 (21 ÷ 3 = 7), 4908 is also divisible by 3. Therefore, 4908 is divisible by 3.
