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 13,447,811, 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 | 13,447,811 | |
| -1 | -13,447,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,447,811.
Example:
1 x 13,447,811 = 13,447,811
and
-1 x -13,447,811 = 13,447,811
Notice both answers equal 13,447,811
With that explanation out of the way, let's continue. Next, we take the number 13,447,811 and divide it by 2:
13,447,811 ÷ 2 = 6,723,905.5
If the quotient is a whole number, then 2 and 6,723,905.5 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 | 13,447,811 | |
| -1 | -13,447,811 |
Now, we try dividing 13,447,811 by 3:
13,447,811 ÷ 3 = 4,482,603.6667
If the quotient is a whole number, then 3 and 4,482,603.6667 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 | 13,447,811 | |
| -1 | -13,447,811 |
Let's try dividing by 4:
13,447,811 ÷ 4 = 3,361,952.75
If the quotient is a whole number, then 4 and 3,361,952.75 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 | 13,447,811 | |
| -1 | 13,447,811 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 89 | 197 | 767 | 1,157 | 2,561 | 5,251 | 11,623 | 17,533 | 68,263 | 151,099 | 227,929 | 1,034,447 | 13,447,811 |
| -1 | -13 | -59 | -89 | -197 | -767 | -1,157 | -2,561 | -5,251 | -11,623 | -17,533 | -68,263 | -151,099 | -227,929 | -1,034,447 | -13,447,811 |
