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 10,210,013, 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 | 10,210,013 | |
| -1 | -10,210,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,210,013.
Example:
1 x 10,210,013 = 10,210,013
and
-1 x -10,210,013 = 10,210,013
Notice both answers equal 10,210,013
With that explanation out of the way, let's continue. Next, we take the number 10,210,013 and divide it by 2:
10,210,013 ÷ 2 = 5,105,006.5
If the quotient is a whole number, then 2 and 5,105,006.5 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 | 10,210,013 | |
| -1 | -10,210,013 |
Now, we try dividing 10,210,013 by 3:
10,210,013 ÷ 3 = 3,403,337.6667
If the quotient is a whole number, then 3 and 3,403,337.6667 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 | 10,210,013 | |
| -1 | -10,210,013 |
Let's try dividing by 4:
10,210,013 ÷ 4 = 2,552,503.25
If the quotient is a whole number, then 4 and 2,552,503.25 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 | 10,210,013 | |
| -1 | 10,210,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 71 | 187 | 769 | 781 | 1,207 | 8,459 | 13,073 | 13,277 | 54,599 | 143,803 | 600,589 | 928,183 | 10,210,013 |
| -1 | -11 | -17 | -71 | -187 | -769 | -781 | -1,207 | -8,459 | -13,073 | -13,277 | -54,599 | -143,803 | -600,589 | -928,183 | -10,210,013 |
