"Smallest prime" would usually be taken as the number 2.
"Smallest whole number" is more problematic, since "whole number" may refer to any of the following:
Even the term "natural numbers" may or may not include zero. Traditionally it doesn't include zero, but according to the Wikipedia article on natural numbers, "There is no universal agreement about whether to include zero in the set of natural numbers".
Because of this ambiguity, it is better to avoid the use of the term "whole number", and instead use more specific terms, for example, "integers", "positive whole numbers" and "non-negative whole numbers".
9998
It is replacing the number by the whole number such that the difference between the number and that whole number is the smallest that it can be.
The largest 5-digit number is 99,999, the smallest is .00001,and the difference is 99,998.99999 .If you only want to consider whole numbers, then the smallest is 10,000and the difference is 89,999 .
100000 - 9999 = 90001
100000 - 999 = 99001

It isn't 1 is. 1 is always the smallest. Can you divide 1 and get a whole number? No a prime number is something that you can divide into, yes you can divide it, making it a negative number, but not a whole number. * * * * * In fact, 1 is NOT a prime (nor a composite), so 2 IS the smallest prime.

It is 2 which is also the only even prime number
