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 13,956,173, 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 | 13,956,173 | |
| -1 | -13,956,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,956,173.
Example:
1 x 13,956,173 = 13,956,173
and
-1 x -13,956,173 = 13,956,173
Notice both answers equal 13,956,173
With that explanation out of the way, let's continue. Next, we take the number 13,956,173 and divide it by 2:
13,956,173 ÷ 2 = 6,978,086.5
If the quotient is a whole number, then 2 and 6,978,086.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,956,173 | |
| -1 | -13,956,173 |
Now, we try dividing 13,956,173 by 3:
13,956,173 ÷ 3 = 4,652,057.6667
If the quotient is a whole number, then 3 and 4,652,057.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,956,173 | |
| -1 | -13,956,173 |
Let's try dividing by 4:
13,956,173 ÷ 4 = 3,489,043.25
If the quotient is a whole number, then 4 and 3,489,043.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,956,173 | |
| -1 | 13,956,173 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 211 | 859 | 1,477 | 2,321 | 6,013 | 9,449 | 16,247 | 66,143 | 181,249 | 1,268,743 | 1,993,739 | 13,956,173 |
| -1 | -7 | -11 | -77 | -211 | -859 | -1,477 | -2,321 | -6,013 | -9,449 | -16,247 | -66,143 | -181,249 | -1,268,743 | -1,993,739 | -13,956,173 |
