The concepts for this exercise are summarized below.
For a complete discussion, read the text.
EXAMPLE:
List all the factors of 30:
Answer: 1,30,2,15,3,10,5,6
For the computer to recognize your answer as correct, you must list the factors in the order
indicated in the example:
- The factors occur in pairs that multiply together to give 30
- 1 goes into 30 evenly, giving the pair 1,30. You must write the smaller number first in each pair.
- 2 goes into 30 evenly, giving the pair 2,15
- 3 goes into 30 evenly, giving the pair 3,10
- 4 doesn't go into 30 evenly
- 5 goes into 30 evenly, giving the pair 5,6
- When you reach a number that's already in the list, you can stop!
- The numbers must be separated by commas; spaces are optional.
