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 17,545,411, 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 | 17,545,411 | |
| -1 | -17,545,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,545,411.
Example:
1 x 17,545,411 = 17,545,411
and
-1 x -17,545,411 = 17,545,411
Notice both answers equal 17,545,411
With that explanation out of the way, let's continue. Next, we take the number 17,545,411 and divide it by 2:
17,545,411 ÷ 2 = 8,772,705.5
If the quotient is a whole number, then 2 and 8,772,705.5 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 | 17,545,411 | |
| -1 | -17,545,411 |
Now, we try dividing 17,545,411 by 3:
17,545,411 ÷ 3 = 5,848,470.3333
If the quotient is a whole number, then 3 and 5,848,470.3333 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 | 17,545,411 | |
| -1 | -17,545,411 |
Let's try dividing by 4:
17,545,411 ÷ 4 = 4,386,352.75
If the quotient is a whole number, then 4 and 4,386,352.75 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 | 17,545,411 | |
| -1 | 17,545,411 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 31 | 169 | 197 | 221 | 403 | 527 | 2,561 | 2,873 | 3,349 | 5,239 | 6,107 | 6,851 | 33,293 | 43,537 | 79,391 | 89,063 | 103,819 | 565,981 | 1,032,083 | 1,349,647 | 17,545,411 |
| -1 | -13 | -17 | -31 | -169 | -197 | -221 | -403 | -527 | -2,561 | -2,873 | -3,349 | -5,239 | -6,107 | -6,851 | -33,293 | -43,537 | -79,391 | -89,063 | -103,819 | -565,981 | -1,032,083 | -1,349,647 | -17,545,411 |
