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 10,302,413, 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 | 10,302,413 | |
| -1 | -10,302,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,302,413.
Example:
1 x 10,302,413 = 10,302,413
and
-1 x -10,302,413 = 10,302,413
Notice both answers equal 10,302,413
With that explanation out of the way, let's continue. Next, we take the number 10,302,413 and divide it by 2:
10,302,413 ÷ 2 = 5,151,206.5
If the quotient is a whole number, then 2 and 5,151,206.5 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 | 10,302,413 | |
| -1 | -10,302,413 |
Now, we try dividing 10,302,413 by 3:
10,302,413 ÷ 3 = 3,434,137.6667
If the quotient is a whole number, then 3 and 3,434,137.6667 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 | 10,302,413 | |
| -1 | -10,302,413 |
Let's try dividing by 4:
10,302,413 ÷ 4 = 2,575,603.25
If the quotient is a whole number, then 4 and 2,575,603.25 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 | 10,302,413 | |
| -1 | 10,302,413 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 43 | 253 | 473 | 947 | 989 | 10,417 | 10,879 | 21,781 | 40,721 | 239,591 | 447,931 | 936,583 | 10,302,413 |
| -1 | -11 | -23 | -43 | -253 | -473 | -947 | -989 | -10,417 | -10,879 | -21,781 | -40,721 | -239,591 | -447,931 | -936,583 | -10,302,413 |
