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 17,357,225, 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 | 17,357,225 | |
| -1 | -17,357,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,357,225.
Example:
1 x 17,357,225 = 17,357,225
and
-1 x -17,357,225 = 17,357,225
Notice both answers equal 17,357,225
With that explanation out of the way, let's continue. Next, we take the number 17,357,225 and divide it by 2:
17,357,225 ÷ 2 = 8,678,612.5
If the quotient is a whole number, then 2 and 8,678,612.5 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 | 17,357,225 | |
| -1 | -17,357,225 |
Now, we try dividing 17,357,225 by 3:
17,357,225 ÷ 3 = 5,785,741.6667
If the quotient is a whole number, then 3 and 5,785,741.6667 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 | 17,357,225 | |
| -1 | -17,357,225 |
Let's try dividing by 4:
17,357,225 ÷ 4 = 4,339,306.25
If the quotient is a whole number, then 4 and 4,339,306.25 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 | 17,357,225 | |
| -1 | 17,357,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 89 | 145 | 269 | 445 | 725 | 1,345 | 2,225 | 2,581 | 6,725 | 7,801 | 12,905 | 23,941 | 39,005 | 64,525 | 119,705 | 195,025 | 598,525 | 694,289 | 3,471,445 | 17,357,225 |
| -1 | -5 | -25 | -29 | -89 | -145 | -269 | -445 | -725 | -1,345 | -2,225 | -2,581 | -6,725 | -7,801 | -12,905 | -23,941 | -39,005 | -64,525 | -119,705 | -195,025 | -598,525 | -694,289 | -3,471,445 | -17,357,225 |
