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 10,017,905, 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 | 10,017,905 | |
| -1 | -10,017,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,017,905.
Example:
1 x 10,017,905 = 10,017,905
and
-1 x -10,017,905 = 10,017,905
Notice both answers equal 10,017,905
With that explanation out of the way, let's continue. Next, we take the number 10,017,905 and divide it by 2:
10,017,905 ÷ 2 = 5,008,952.5
If the quotient is a whole number, then 2 and 5,008,952.5 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 | 10,017,905 | |
| -1 | -10,017,905 |
Now, we try dividing 10,017,905 by 3:
10,017,905 ÷ 3 = 3,339,301.6667
If the quotient is a whole number, then 3 and 3,339,301.6667 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 | 10,017,905 | |
| -1 | -10,017,905 |
Let's try dividing by 4:
10,017,905 ÷ 4 = 2,504,476.25
If the quotient is a whole number, then 4 and 2,504,476.25 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 | 10,017,905 | |
| -1 | 10,017,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 145 | 295 | 1,171 | 1,711 | 5,855 | 8,555 | 33,959 | 69,089 | 169,795 | 345,445 | 2,003,581 | 10,017,905 |
| -1 | -5 | -29 | -59 | -145 | -295 | -1,171 | -1,711 | -5,855 | -8,555 | -33,959 | -69,089 | -169,795 | -345,445 | -2,003,581 | -10,017,905 |
