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 17,223,167, 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 | 17,223,167 | |
| -1 | -17,223,167 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,223,167.
Example:
1 x 17,223,167 = 17,223,167
and
-1 x -17,223,167 = 17,223,167
Notice both answers equal 17,223,167
With that explanation out of the way, let's continue. Next, we take the number 17,223,167 and divide it by 2:
17,223,167 ÷ 2 = 8,611,583.5
If the quotient is a whole number, then 2 and 8,611,583.5 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 | 17,223,167 | |
| -1 | -17,223,167 |
Now, we try dividing 17,223,167 by 3:
17,223,167 ÷ 3 = 5,741,055.6667
If the quotient is a whole number, then 3 and 5,741,055.6667 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 | 17,223,167 | |
| -1 | -17,223,167 |
Let's try dividing by 4:
17,223,167 ÷ 4 = 4,305,791.75
If the quotient is a whole number, then 4 and 4,305,791.75 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 | 17,223,167 | |
| -1 | 17,223,167 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 61 | 481 | 587 | 793 | 2,257 | 7,631 | 21,719 | 29,341 | 35,807 | 282,347 | 465,491 | 1,324,859 | 17,223,167 |
| -1 | -13 | -37 | -61 | -481 | -587 | -793 | -2,257 | -7,631 | -21,719 | -29,341 | -35,807 | -282,347 | -465,491 | -1,324,859 | -17,223,167 |
