WebDivisibility by 3 or 9 [ edit] First, take any number (for this example it will be 492) and add together each digit in the number (4 + 9 + 2 = 15). Then take that sum (15) and determine if it is divisible by 3. The original number is divisible by 3 (or 9) if and only if the sum of its digits is divisible by 3 (or 9). WebHere is the beginning list of numbers divisible by 3, starting with the lowest number which is 3 itself: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, etc. As you can see from the list, the numbers are intervals of 3. You can keep adding to the list and make it as long as you want by simply adding 3 to the previous number. Numbers Divisible By Calculator
WebHence 1,481,481,468 is divisible by 3. Applying the divisibility test for 4, we get that the last two digits, 68, is divisible by 4. Hence 1,481,481,468 is also divisible by 4. Now, since we know that 1,481,481,468 is divisible by both 3 and 4, it is divisible by 12.

WebOut of every 30 such multiples 15 are divisible by 2, of the remaining 15, 5 are divisible by 3, and of the remaining 10, 2 are divisible by 5 (note the pattern). So this leaves 8 in every 30 divisible by 7 alone. 285 = 9 ⋅ 30 + 15. So we have 8 ⋅ 9 = 72 such multiples up to 270, and it is easy to check 4 more in the final 15.
Web2 aug. 2024 · Use the math formula based on the famous Triangular number formula for summing the integers between 1 and n, i.e. n (n+1) / 2. So, for n = 4, the sum is 4 * 5 / 2 = 10.
