The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 .
(1+15)*15/2first plus last times number of numbers then divide by two
Which of these numbers is closest to 500?
The sum of the first five whole numbers is 10.
14 is immediately between the whole numbers of 13 and 15.
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.
1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

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
1, 3, 5 & 15 all divide 15 and 120 exactly.
Which of these numbers is closest to 500?
If you divide a whole number by 15, the remainder can be any number between 0 and 14.
1 and 5.
