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 13,665,845, 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 | 13,665,845 | |
| -1 | -13,665,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,665,845.
Example:
1 x 13,665,845 = 13,665,845
and
-1 x -13,665,845 = 13,665,845
Notice both answers equal 13,665,845
With that explanation out of the way, let's continue. Next, we take the number 13,665,845 and divide it by 2:
13,665,845 ÷ 2 = 6,832,922.5
If the quotient is a whole number, then 2 and 6,832,922.5 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 | 13,665,845 | |
| -1 | -13,665,845 |
Now, we try dividing 13,665,845 by 3:
13,665,845 ÷ 3 = 4,555,281.6667
If the quotient is a whole number, then 3 and 4,555,281.6667 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 | 13,665,845 | |
| -1 | -13,665,845 |
Let's try dividing by 4:
13,665,845 ÷ 4 = 3,416,461.25
If the quotient is a whole number, then 4 and 3,416,461.25 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 | 13,665,845 | |
| -1 | 13,665,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 97 | 485 | 1,483 | 1,843 | 7,415 | 9,215 | 28,177 | 140,885 | 143,851 | 719,255 | 2,733,169 | 13,665,845 |
| -1 | -5 | -19 | -95 | -97 | -485 | -1,483 | -1,843 | -7,415 | -9,215 | -28,177 | -140,885 | -143,851 | -719,255 | -2,733,169 | -13,665,845 |
