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 13,196,711, 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 | 13,196,711 | |
| -1 | -13,196,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,196,711.
Example:
1 x 13,196,711 = 13,196,711
and
-1 x -13,196,711 = 13,196,711
Notice both answers equal 13,196,711
With that explanation out of the way, let's continue. Next, we take the number 13,196,711 and divide it by 2:
13,196,711 ÷ 2 = 6,598,355.5
If the quotient is a whole number, then 2 and 6,598,355.5 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 | 13,196,711 | |
| -1 | -13,196,711 |
Now, we try dividing 13,196,711 by 3:
13,196,711 ÷ 3 = 4,398,903.6667
If the quotient is a whole number, then 3 and 4,398,903.6667 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 | 13,196,711 | |
| -1 | -13,196,711 |
Let's try dividing by 4:
13,196,711 ÷ 4 = 3,299,177.75
If the quotient is a whole number, then 4 and 3,299,177.75 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 | 13,196,711 | |
| -1 | 13,196,711 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 41 | 319 | 451 | 1,009 | 1,189 | 11,099 | 13,079 | 29,261 | 41,369 | 321,871 | 455,059 | 1,199,701 | 13,196,711 |
| -1 | -11 | -29 | -41 | -319 | -451 | -1,009 | -1,189 | -11,099 | -13,079 | -29,261 | -41,369 | -321,871 | -455,059 | -1,199,701 | -13,196,711 |
