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 17,610,725, 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 | 17,610,725 | |
| -1 | -17,610,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,610,725.
Example:
1 x 17,610,725 = 17,610,725
and
-1 x -17,610,725 = 17,610,725
Notice both answers equal 17,610,725
With that explanation out of the way, let's continue. Next, we take the number 17,610,725 and divide it by 2:
17,610,725 ÷ 2 = 8,805,362.5
If the quotient is a whole number, then 2 and 8,805,362.5 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 | 17,610,725 | |
| -1 | -17,610,725 |
Now, we try dividing 17,610,725 by 3:
17,610,725 ÷ 3 = 5,870,241.6667
If the quotient is a whole number, then 3 and 5,870,241.6667 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 | 17,610,725 | |
| -1 | -17,610,725 |
Let's try dividing by 4:
17,610,725 ÷ 4 = 4,402,681.25
If the quotient is a whole number, then 4 and 4,402,681.25 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 | 17,610,725 | |
| -1 | 17,610,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 25 | 55 | 85 | 187 | 275 | 425 | 935 | 3,767 | 4,675 | 18,835 | 41,437 | 64,039 | 94,175 | 207,185 | 320,195 | 704,429 | 1,035,925 | 1,600,975 | 3,522,145 | 17,610,725 |
| -1 | -5 | -11 | -17 | -25 | -55 | -85 | -187 | -275 | -425 | -935 | -3,767 | -4,675 | -18,835 | -41,437 | -64,039 | -94,175 | -207,185 | -320,195 | -704,429 | -1,035,925 | -1,600,975 | -3,522,145 | -17,610,725 |
