14 is immediately between the whole numbers of 13 and 15.
The sum of the first five whole numbers is 10.
1, 3, 5, 15
It is 5.
Because 1, 3, 5 and 15 are the only positive whole numbers that will divide evenly into 15 with no remainder.

The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 .
Factors are numbers which divide another number exactly. The factors of 11 are 1 and 11. The factors of 15 are 1, 3, 5 and 15. So the only common factor of 11 and 15 is 1.
(1+15)*15/2first plus last times number of numbers then divide by two
The whole numbers between 10 and 15 are 11, 12, 13, and 14. These numbers do not include 10 and 15 themselves, as they are not considered "between" in this context.
1, 3, 5 & 15 all divide 15 and 120 exactly.
75 cannot go into 15 any whole number of times because 75 is greater than 15. If you were to divide 15 by 75, the result would be a fraction (15/75), which simplifies to 1/5. Thus, 75 goes into 15 zero times in whole numbers.
