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 10,012,411, 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 | 10,012,411 | |
| -1 | -10,012,411 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,012,411.
Example:
1 x 10,012,411 = 10,012,411
and
-1 x -10,012,411 = 10,012,411
Notice both answers equal 10,012,411
With that explanation out of the way, let's continue. Next, we take the number 10,012,411 and divide it by 2:
10,012,411 ÷ 2 = 5,006,205.5
If the quotient is a whole number, then 2 and 5,006,205.5 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 | 10,012,411 | |
| -1 | -10,012,411 |
Now, we try dividing 10,012,411 by 3:
10,012,411 ÷ 3 = 3,337,470.3333
If the quotient is a whole number, then 3 and 3,337,470.3333 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 | 10,012,411 | |
| -1 | -10,012,411 |
Let's try dividing by 4:
10,012,411 ÷ 4 = 2,503,102.75
If the quotient is a whole number, then 4 and 2,503,102.75 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 | 10,012,411 | |
| -1 | 10,012,411 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 89 | 191 | 589 | 1,691 | 2,759 | 3,629 | 5,921 | 16,999 | 52,421 | 112,499 | 322,981 | 526,969 | 10,012,411 |
| -1 | -19 | -31 | -89 | -191 | -589 | -1,691 | -2,759 | -3,629 | -5,921 | -16,999 | -52,421 | -112,499 | -322,981 | -526,969 | -10,012,411 |
