These numbers divide into 15 evenly: 1 3 5 and 15.
The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 .
Mixed numbers can't be whole numbers.
(1+15)*15/2first plus last times number of numbers then divide by two
The sum of the first five whole numbers is 10.
1, 3, 5, 15
It is 5.
15÷4=3.75
Because 1, 3, 5 and 15 are the only positive whole numbers that will divide evenly into 15 with no remainder.
These numbers divide into 15 evenly: 1 3 5 and 15.
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 .
Mixed numbers can't be whole numbers.
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.
