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 17,718,625, 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 | 17,718,625 | |
| -1 | -17,718,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,718,625.
Example:
1 x 17,718,625 = 17,718,625
and
-1 x -17,718,625 = 17,718,625
Notice both answers equal 17,718,625
With that explanation out of the way, let's continue. Next, we take the number 17,718,625 and divide it by 2:
17,718,625 ÷ 2 = 8,859,312.5
If the quotient is a whole number, then 2 and 8,859,312.5 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 | 17,718,625 | |
| -1 | -17,718,625 |
Now, we try dividing 17,718,625 by 3:
17,718,625 ÷ 3 = 5,906,208.3333
If the quotient is a whole number, then 3 and 5,906,208.3333 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 | 17,718,625 | |
| -1 | -17,718,625 |
Let's try dividing by 4:
17,718,625 ÷ 4 = 4,429,656.25
If the quotient is a whole number, then 4 and 4,429,656.25 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 | 17,718,625 | |
| -1 | 17,718,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 125 | 575 | 2,875 | 6,163 | 30,815 | 141,749 | 154,075 | 708,745 | 770,375 | 3,543,725 | 17,718,625 |
| -1 | -5 | -23 | -25 | -115 | -125 | -575 | -2,875 | -6,163 | -30,815 | -141,749 | -154,075 | -708,745 | -770,375 | -3,543,725 | -17,718,625 |
