No.
No, because there is no greatest integer.
The smallest positive integer is 1. 1 is the multiplicative identity; ie anything times 1 is itself. The greatest negative integer is the most positive negative integer which is -1. Therefore the product of the greatest negative integer and the smallest positive integer is the greatest negative integer which is -1.
There is no greatest integer. Whatever integer you think is greatest, you can always add one (1) to it and get a larger one.
The greatest factor of any integer is the integer itself.
The greatest factor of any integer is the integer itself.
-2 is the greatest negative even integer.
The greatest factor of 99 is itself, which is 99. The greatest factor of any integer is the integer itself.
The greatest integer function, often denoted as ⌊x⌋, gives the largest integer less than or equal to x. For 0.7, the greatest integer is 0, since 0 is the largest integer that is less than or equal to 0.7. Thus, ⌊0.7⌋ = 0.
The greatest integer that will divide evenly into 36 is 36. 18 is 36's greatest proper factor.
There is none, because there is always a greater integer.
You cannot, because there is no greatest integer. If you thought you had one, then move just one unit to the right and you will have an integer which is greater.
No. For any integer, you can add one to get an even greater integer.
