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 10,322,213, 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 | 10,322,213 | |
| -1 | -10,322,213 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,322,213.
Example:
1 x 10,322,213 = 10,322,213
and
-1 x -10,322,213 = 10,322,213
Notice both answers equal 10,322,213
With that explanation out of the way, let's continue. Next, we take the number 10,322,213 and divide it by 2:
10,322,213 ÷ 2 = 5,161,106.5
If the quotient is a whole number, then 2 and 5,161,106.5 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 | 10,322,213 | |
| -1 | -10,322,213 |
Now, we try dividing 10,322,213 by 3:
10,322,213 ÷ 3 = 3,440,737.6667
If the quotient is a whole number, then 3 and 3,440,737.6667 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 | 10,322,213 | |
| -1 | -10,322,213 |
Let's try dividing by 4:
10,322,213 ÷ 4 = 2,580,553.25
If the quotient is a whole number, then 4 and 2,580,553.25 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 | 10,322,213 | |
| -1 | 10,322,213 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 191 | 289 | 2,101 | 3,179 | 3,247 | 4,913 | 35,717 | 54,043 | 55,199 | 607,189 | 938,383 | 10,322,213 |
| -1 | -11 | -17 | -187 | -191 | -289 | -2,101 | -3,179 | -3,247 | -4,913 | -35,717 | -54,043 | -55,199 | -607,189 | -938,383 | -10,322,213 |
