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 13,842,845, 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 | 13,842,845 | |
| -1 | -13,842,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,842,845.
Example:
1 x 13,842,845 = 13,842,845
and
-1 x -13,842,845 = 13,842,845
Notice both answers equal 13,842,845
With that explanation out of the way, let's continue. Next, we take the number 13,842,845 and divide it by 2:
13,842,845 ÷ 2 = 6,921,422.5
If the quotient is a whole number, then 2 and 6,921,422.5 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 | 13,842,845 | |
| -1 | -13,842,845 |
Now, we try dividing 13,842,845 by 3:
13,842,845 ÷ 3 = 4,614,281.6667
If the quotient is a whole number, then 3 and 4,614,281.6667 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 | 13,842,845 | |
| -1 | -13,842,845 |
Let's try dividing by 4:
13,842,845 ÷ 4 = 3,460,711.25
If the quotient is a whole number, then 4 and 3,460,711.25 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 | 13,842,845 | |
| -1 | 13,842,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 149 | 745 | 1,093 | 2,533 | 5,465 | 12,665 | 18,581 | 92,905 | 162,857 | 814,285 | 2,768,569 | 13,842,845 |
| -1 | -5 | -17 | -85 | -149 | -745 | -1,093 | -2,533 | -5,465 | -12,665 | -18,581 | -92,905 | -162,857 | -814,285 | -2,768,569 | -13,842,845 |
