1, 2, 5 and 10
It must be a multiple of ten, so it must have the factors 1, 2, 5 and 10.
12 is the only two digit number which is a factor of 12.

973
The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
5 and 10
It must be a multiple of ten, so it must have the factors 1, 2, 5 and 10.
The two-digit factors of 100 and 1000 are all composite.
Both 10 and 20 are two-digit numbers that are factors of 20.
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.
Sure. Any 1-digit number contains only one-digit numbers as factors. Any larger number, on the other hand, contains itself as a factor, so these can be excluded.
To find the largest 2-digit number that is a factor of 3375, we need to factorize 3375 into its prime factors. 3375 can be expressed as 3^3 * 5^3. To find the largest 2-digit number that is a factor, we need to consider the factors that are multiples of both 3 and 5. The largest 2-digit number that fits this criteria is 75, which is 3 * 5^2.
i do not really know because i am the one that asked the quetion.
Every six-digit number is greater than any five-digit number.
720.
There is no single digit number greater than 9. After 9 is 10, which is a double-digit number.
2 is a prime number and has no factors other than 1 and itself.
