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 9,926,845, 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 | 9,926,845 | |
| -1 | -9,926,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,926,845.
Example:
1 x 9,926,845 = 9,926,845
and
-1 x -9,926,845 = 9,926,845
Notice both answers equal 9,926,845
With that explanation out of the way, let's continue. Next, we take the number 9,926,845 and divide it by 2:
9,926,845 ÷ 2 = 4,963,422.5
If the quotient is a whole number, then 2 and 4,963,422.5 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 | 9,926,845 | |
| -1 | -9,926,845 |
Now, we try dividing 9,926,845 by 3:
9,926,845 ÷ 3 = 3,308,948.3333
If the quotient is a whole number, then 3 and 3,308,948.3333 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 | 9,926,845 | |
| -1 | -9,926,845 |
Let's try dividing by 4:
9,926,845 ÷ 4 = 2,481,711.25
If the quotient is a whole number, then 4 and 2,481,711.25 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 | 9,926,845 | |
| -1 | 9,926,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 223 | 307 | 1,115 | 1,535 | 6,467 | 8,903 | 32,335 | 44,515 | 68,461 | 342,305 | 1,985,369 | 9,926,845 |
| -1 | -5 | -29 | -145 | -223 | -307 | -1,115 | -1,535 | -6,467 | -8,903 | -32,335 | -44,515 | -68,461 | -342,305 | -1,985,369 | -9,926,845 |
