If the sum of the digits of a given number equals nine or a multiple of nine, nine is a factor of that number.

If that is the case, then three is a factor of the original number.

No number satisfies all of those conditions.

No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.

No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.

Add up the digits of the given number. If they total a multiple of three, the number has three as a factor.

If the last two digits of your target number are a multiple of 4, 4 is a factor of the whole number.

450 or 900

21 or 35

If you add all the digits up, and the total equals a number that 3 can go in, then it's a factor of 3.

I think you might mean "multiple." If the sum of a number's digits is a multiple of 9, the original number is as well. If you want to know how you know if a number is a factor of 9, memorize the numbers 1, 3 and 9.

189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.

The number is 35.

No. A factor goes into a number. A number goes into a multiple. They have an inverse relationship in the sense that if A is a multiple of B, then B is a factor of A.

You can reduce the number by known factors to make it more manageable. Plus there are tricks for different numbers: If the number is even, then 2 is a factor. If the digits add up to a multiple of 3 then 3 is a factor. If the ones digit is a 5 or 0 (with a tens digit greater than or equal to 1), then 5 is a factor. If the ones digit is a 0 then 10 is a factor. If the digits have the property that the first minus the second, plus the third, minus the fourth, (alternating signs) equals 0, then 11 is a factor. There are other tricks but these factors would be the most common.

If the number ends in 0, 2, 4, 6 or 8, it's a multiple of 2.

yes 72/3 equals 24. an easy way to find out if a number is divisible by three is to add up all the digits. if the sum of the digits is divisible by three, the whole number is divisible by three.

24 divided by three equals 8 divided by four equals 6 2 plus 4 equals 6

No. A number cannot be both a factor and a multiple of another number. A number can be multiple and factor of itself, but nothing else.
