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 163,044,167, 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 | 163,044,167 | |
| -1 | -163,044,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,044,167.
Example:
1 x 163,044,167 = 163,044,167
and
-1 x -163,044,167 = 163,044,167
Notice both answers equal 163,044,167
With that explanation out of the way, let's continue. Next, we take the number 163,044,167 and divide it by 2:
163,044,167 ÷ 2 = 81,522,083.5
If the quotient is a whole number, then 2 and 81,522,083.5 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 | 163,044,167 | |
| -1 | -163,044,167 |
Now, we try dividing 163,044,167 by 3:
163,044,167 ÷ 3 = 54,348,055.6667
If the quotient is a whole number, then 3 and 54,348,055.6667 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 | 163,044,167 | |
| -1 | -163,044,167 |
Let's try dividing by 4:
163,044,167 ÷ 4 = 40,761,041.75
If the quotient is a whole number, then 4 and 40,761,041.75 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 | 163,044,167 | |
| -1 | 163,044,167 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 41 | 143 | 451 | 533 | 5,863 | 27,809 | 305,899 | 361,517 | 1,140,169 | 3,976,687 | 12,541,859 | 14,822,197 | 163,044,167 |
| -1 | -11 | -13 | -41 | -143 | -451 | -533 | -5,863 | -27,809 | -305,899 | -361,517 | -1,140,169 | -3,976,687 | -12,541,859 | -14,822,197 | -163,044,167 |
