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 17,806,705, 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 | 17,806,705 | |
| -1 | -17,806,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,806,705.
Example:
1 x 17,806,705 = 17,806,705
and
-1 x -17,806,705 = 17,806,705
Notice both answers equal 17,806,705
With that explanation out of the way, let's continue. Next, we take the number 17,806,705 and divide it by 2:
17,806,705 ÷ 2 = 8,903,352.5
If the quotient is a whole number, then 2 and 8,903,352.5 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 | 17,806,705 | |
| -1 | -17,806,705 |
Now, we try dividing 17,806,705 by 3:
17,806,705 ÷ 3 = 5,935,568.3333
If the quotient is a whole number, then 3 and 5,935,568.3333 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 | 17,806,705 | |
| -1 | -17,806,705 |
Let's try dividing by 4:
17,806,705 ÷ 4 = 4,451,676.25
If the quotient is a whole number, then 4 and 4,451,676.25 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 | 17,806,705 | |
| -1 | 17,806,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 26,777 | 133,885 | 187,439 | 508,763 | 937,195 | 2,543,815 | 3,561,341 | 17,806,705 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -26,777 | -133,885 | -187,439 | -508,763 | -937,195 | -2,543,815 | -3,561,341 | -17,806,705 |
