# What Are the Factors of 315?

The factors of 315 are 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315.

Calcating the factors of 315 is straightforward. 1 and 315 are the first two factors.

1. Try 1. 1 x 315 = 315, so put these into our factor list.
 1 ... 315

2. Take 2... no good. 315/2 isn't a whole number. So we skip 2.

3. Now take 3. 3 x 105 = 315, so now we put these in our list of factors.
 1 3 ... 105 315

4. Next try 4... no luck. 315/4 isn't a whole number. So we skip 4.

5. Now try 5. 5 x 63 = 315, so put these into our factor list.
 1 3 5 ... 63 105 315

6. Try 6... no good. 315/6 isn't a whole number. So we skip 6.

7. Take 7. 7 x 45 = 315, so now we put these in our list of factors.
 1 3 5 7 ... 45 63 105 315

8. Now take 8... no luck. 315/8 isn't a whole number. So we skip 8.

9. Next try 9. 9 x 35 = 315, so put these into our factor list.
 1 3 5 7 9 ... 35 45 63 105 315

10. Now try 10... no good. 315/10 isn't a whole number. So we skip 10.

11. Try 11... no. 315/11 isn't a whole number. So we skip 11.

12. Take 12... no luck. 315/12 isn't a whole number. So we skip 12.

13. Now take 13... nope! 315/13 isn't a whole number. So we skip 13.

14. Next try 14... no good. 315/14 isn't a whole number. So we skip 14.

15. Now try 15. 15 x 21 = 315, so now we put these in our list of factors.
 1 3 5 7 9 15 ... 21 35 45 63 105 315

16. Try 16... no luck. 315/16 isn't a whole number. So we skip 16.

17. Take 17... nope! 315/17 isn't a whole number. So we skip 17.

18. Now take 18... no good. 315/18 isn't a whole number. So we skip 18.

19. Now, since we don't have any more numbers to try, we're done!
 1 3 5 7 9 15 21 35 45 63 105 315
