Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 139,704, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 139,704 | |
| -1 | -139,704 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 139,704.
Example:
1 x 139,704 = 139,704
and
-1 x -139,704 = 139,704
Notice both answers equal 139,704
With that explanation out of the way, let's continue. Next, we take the number 139,704 and divide it by 2:
139,704 ÷ 2 = 69,852
If the quotient is a whole number, then 2 and 69,852 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 69,852 | 139,704 | |
| -1 | -2 | -69,852 | -139,704 |
Now, we try dividing 139,704 by 3:
139,704 ÷ 3 = 46,568
If the quotient is a whole number, then 3 and 46,568 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 46,568 | 69,852 | 139,704 | |
| -1 | -2 | -3 | -46,568 | -69,852 | -139,704 |
Let's try dividing by 4:
139,704 ÷ 4 = 34,926
If the quotient is a whole number, then 4 and 34,926 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
| 1 | 2 | 3 | 4 | 34,926 | 46,568 | 69,852 | 139,704 | |
| -1 | -2 | -3 | -4 | -34,926 | -46,568 | -69,852 | 139,704 |
If you did it right, you will end up with this table:
| 1 | 2 | 3 | 4 | 6 | 8 | 12 | 24 | 5,821 | 11,642 | 17,463 | 23,284 | 34,926 | 46,568 | 69,852 | 139,704 |
| -1 | -2 | -3 | -4 | -6 | -8 | -12 | -24 | -5,821 | -11,642 | -17,463 | -23,284 | -34,926 | -46,568 | -69,852 | -139,704 |
