The factors of 35 are 1, 5, 7, 35.
All of them are odd.
7 and 35 are multiples of 7.
5 has a digit sum equal to 5.
No number satisfies all of the conditions.
It doesn't always. It's true only if the 4-digit numbers are mirror images of each other.
There is no 1-digit number that is equal to 14 and 28.
No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
No, a multiple of 6 cannot have a ones digit equal to 3. The ones digit of a multiple of 6 will always be even, either 0, 2, 4, 6, or 8, because 6 is divisible by 2.

198 is the greatest three-digit even number that has no factor equal to 4.
102
998
As a general rule, multiples tend to be larger than factors. This is not always true. 9 is a factor of 27. 6 is a multiple of 3. The important distinction is in the relationship to the number they are factors or multiples of. A factor will be equal to or lesser than the number. A multiple will be equal to or greater than the number.
The only number that is both a multiple of a number and a factor of that same number is the number itself. Multiples of a number are equal to or bigger than the number, while factors are equal to or smaller than the number.
4 is not a factor of 998
a multiple
It doesn't always. It's true only if the 4-digit numbers are mirror images of each other.

No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
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.
Yes. 12 * 9 = 108. 108 is a number made up from 3 digits.
