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 17,512,675, 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 | 17,512,675 | |
| -1 | -17,512,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,512,675.
Example:
1 x 17,512,675 = 17,512,675
and
-1 x -17,512,675 = 17,512,675
Notice both answers equal 17,512,675
With that explanation out of the way, let's continue. Next, we take the number 17,512,675 and divide it by 2:
17,512,675 ÷ 2 = 8,756,337.5
If the quotient is a whole number, then 2 and 8,756,337.5 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 | 17,512,675 | |
| -1 | -17,512,675 |
Now, we try dividing 17,512,675 by 3:
17,512,675 ÷ 3 = 5,837,558.3333
If the quotient is a whole number, then 3 and 5,837,558.3333 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 | 17,512,675 | |
| -1 | -17,512,675 |
Let's try dividing by 4:
17,512,675 ÷ 4 = 4,378,168.75
If the quotient is a whole number, then 4 and 4,378,168.75 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 | 17,512,675 | |
| -1 | 17,512,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 59 | 155 | 295 | 383 | 775 | 1,475 | 1,829 | 1,915 | 9,145 | 9,575 | 11,873 | 22,597 | 45,725 | 59,365 | 112,985 | 296,825 | 564,925 | 700,507 | 3,502,535 | 17,512,675 |
| -1 | -5 | -25 | -31 | -59 | -155 | -295 | -383 | -775 | -1,475 | -1,829 | -1,915 | -9,145 | -9,575 | -11,873 | -22,597 | -45,725 | -59,365 | -112,985 | -296,825 | -564,925 | -700,507 | -3,502,535 | -17,512,675 |
