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 13,168,183, 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 | 13,168,183 | |
| -1 | -13,168,183 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,168,183.
Example:
1 x 13,168,183 = 13,168,183
and
-1 x -13,168,183 = 13,168,183
Notice both answers equal 13,168,183
With that explanation out of the way, let's continue. Next, we take the number 13,168,183 and divide it by 2:
13,168,183 ÷ 2 = 6,584,091.5
If the quotient is a whole number, then 2 and 6,584,091.5 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 | 13,168,183 | |
| -1 | -13,168,183 |
Now, we try dividing 13,168,183 by 3:
13,168,183 ÷ 3 = 4,389,394.3333
If the quotient is a whole number, then 3 and 4,389,394.3333 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 | 13,168,183 | |
| -1 | -13,168,183 |
Let's try dividing by 4:
13,168,183 ÷ 4 = 3,292,045.75
If the quotient is a whole number, then 4 and 3,292,045.75 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 | 13,168,183 | |
| -1 | 13,168,183 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 239 | 463 | 1,673 | 3,241 | 4,063 | 7,871 | 28,441 | 55,097 | 110,657 | 774,599 | 1,881,169 | 13,168,183 |
| -1 | -7 | -17 | -119 | -239 | -463 | -1,673 | -3,241 | -4,063 | -7,871 | -28,441 | -55,097 | -110,657 | -774,599 | -1,881,169 | -13,168,183 |
