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 17,207,701, 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 | 17,207,701 | |
| -1 | -17,207,701 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,207,701.
Example:
1 x 17,207,701 = 17,207,701
and
-1 x -17,207,701 = 17,207,701
Notice both answers equal 17,207,701
With that explanation out of the way, let's continue. Next, we take the number 17,207,701 and divide it by 2:
17,207,701 ÷ 2 = 8,603,850.5
If the quotient is a whole number, then 2 and 8,603,850.5 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 | 17,207,701 | |
| -1 | -17,207,701 |
Now, we try dividing 17,207,701 by 3:
17,207,701 ÷ 3 = 5,735,900.3333
If the quotient is a whole number, then 3 and 5,735,900.3333 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 | 17,207,701 | |
| -1 | -17,207,701 |
Let's try dividing by 4:
17,207,701 ÷ 4 = 4,301,925.25
If the quotient is a whole number, then 4 and 4,301,925.25 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 | 17,207,701 | |
| -1 | 17,207,701 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 37 | 79 | 203 | 259 | 553 | 841 | 1,073 | 2,291 | 2,923 | 5,887 | 7,511 | 16,037 | 20,461 | 31,117 | 66,439 | 84,767 | 217,819 | 465,073 | 593,369 | 2,458,243 | 17,207,701 |
| -1 | -7 | -29 | -37 | -79 | -203 | -259 | -553 | -841 | -1,073 | -2,291 | -2,923 | -5,887 | -7,511 | -16,037 | -20,461 | -31,117 | -66,439 | -84,767 | -217,819 | -465,073 | -593,369 | -2,458,243 | -17,207,701 |
