# What Are the Factors of 140?

The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140.

Calcating the factors of 140 is straightforward. Take 140 and the number 1. Those are the first two factors.

1. Try 1. 1 x 140 = 140, so put these into our factor list.
 1 ... 140

2. Take 2. 2 x 70 = 140, which means we add these to our factor list.
 1 2 ... 70 140

3. Now take 3... no. 140/3 isn't a whole number. So we skip 3.

4. Next try 4. 4 x 35 = 140, so we add these to our list of factors.
 1 2 4 ... 35 70 140

5. Now try 5. 5 x 28 = 140, so put these into our factor list.
 1 2 4 5 ... 28 35 70 140

6. Try 6... no good. 140/6 isn't a whole number. So we skip 6.

7. Take 7. 7 x 20 = 140, so now we put these in our list of factors.
 1 2 4 5 7 ... 20 28 35 70 140

8. Now take 8... no luck. 140/8 isn't a whole number. So we skip 8.

9. Next try 9... nope! 140/9 isn't a whole number. So we skip 9.

10. Now try 10. 10 x 14 = 140, which means we add these to our factor list.
 1 2 4 5 7 10 ... 14 20 28 35 70 140

11. Try 11... no. 140/11 isn't a whole number. So we skip 11.

12. Take 12... no luck. 140/12 isn't a whole number. So we skip 12.

13. Now, since we don't have any more numbers to try, we're done!
 1 2 4 5 7 10 14 20 28 35 70 140
