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 17,226,355, 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 | 17,226,355 | |
| -1 | -17,226,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,226,355.
Example:
1 x 17,226,355 = 17,226,355
and
-1 x -17,226,355 = 17,226,355
Notice both answers equal 17,226,355
With that explanation out of the way, let's continue. Next, we take the number 17,226,355 and divide it by 2:
17,226,355 ÷ 2 = 8,613,177.5
If the quotient is a whole number, then 2 and 8,613,177.5 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 | 17,226,355 | |
| -1 | -17,226,355 |
Now, we try dividing 17,226,355 by 3:
17,226,355 ÷ 3 = 5,742,118.3333
If the quotient is a whole number, then 3 and 5,742,118.3333 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 | 17,226,355 | |
| -1 | -17,226,355 |
Let's try dividing by 4:
17,226,355 ÷ 4 = 4,306,588.75
If the quotient is a whole number, then 4 and 4,306,588.75 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 | 17,226,355 | |
| -1 | 17,226,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 3,485 | 4,943 | 24,715 | 84,031 | 202,663 | 420,155 | 1,013,315 | 3,445,271 | 17,226,355 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -3,485 | -4,943 | -24,715 | -84,031 | -202,663 | -420,155 | -1,013,315 | -3,445,271 | -17,226,355 |
