A factor
A multiple.
Odd
A decimal without a remainder is a whole number or integer.
A factor is a number such that it evenly divides a number. Example: Algebra: Let's say that we have a number, X. A factor of X would be a number (let's call this number f) such that it would divide X evenly without leaving a remainder. So, you can write X/f = n (where n is an integer) Arithmetic: Let's say that we have a number 9. A factor of 9 would be a number such that it would divide 9 evenly without leaving a remainder. By this definition, a factor of 9 would be 3 because 9/3 = 3<-- notice that this answer, 3, is an integer. Also, notice that this division does not leave behind any remainder. An example of a number that is NOT a factor of another number: Let's say that we have a number 9. A non-factor of 9 would be 6 because 9/6 does not leave behind a nice, whole number.
The number 41 is a prime number, which means it can only be divided evenly by itself and 1. In other words, the only factors of 41 are 1 and 41. Therefore, there is no other whole number that can divide into 41 without leaving a remainder.
Odd
IF they are integers, then the first number is a multiple of the second and the second is a factor of the first.
Yes.
Divide the upper limit of the range by A. Throw out the remainder, if any. Let's call what's left B. Divide the lower limit of the range by A. Throw out the remainder, if any. Let's call what's left C. Subtract C from B. The difference is the number of multiples within the range. 41 ÷ 5 = 8.2 --> B = 8 9 ÷ 5 = 1.8 --> C = 1 B - C = 8 - 1 = 7
We call this left over number the remainder.

A number without a decimal would be a number without a fraction - hence it would be a "whole number".
