2 is a prime number and has no factors other than 1 and itself.
It is a fraction whose denominator has a factor other than 2 or 5.
When one factor is less than one, the product will be less than the other factor.

It is a fraction whose denominator has a factor other than 2 or 5.
4.23 is greater than 4.13 Notice how the digit that is a 2 is greater than the digit that is a 1, and the other digits are identical.
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.
452, 894. None other that I can think of
The product is less than the other factor. For example: 0.5 x 6 = 3. 3 is less than the factor that is greater than 1 (which is 6).
When one factor is less than one, the product will be less than the other factor.
There is no common factor as you have to have at least 2 numbers to have a "common" factor. The greatest factor of 225 other than 225 is 75

No. Look at the first digit after the decimal point, which is the first digit other than zero, and compare those.
