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 13,101,011, 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 | 13,101,011 | |
| -1 | -13,101,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,101,011.
Example:
1 x 13,101,011 = 13,101,011
and
-1 x -13,101,011 = 13,101,011
Notice both answers equal 13,101,011
With that explanation out of the way, let's continue. Next, we take the number 13,101,011 and divide it by 2:
13,101,011 ÷ 2 = 6,550,505.5
If the quotient is a whole number, then 2 and 6,550,505.5 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 | 13,101,011 | |
| -1 | -13,101,011 |
Now, we try dividing 13,101,011 by 3:
13,101,011 ÷ 3 = 4,367,003.6667
If the quotient is a whole number, then 3 and 4,367,003.6667 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 | 13,101,011 | |
| -1 | -13,101,011 |
Let's try dividing by 4:
13,101,011 ÷ 4 = 3,275,252.75
If the quotient is a whole number, then 4 and 3,275,252.75 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 | 13,101,011 | |
| -1 | 13,101,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 5,867 | 41,069 | 64,537 | 170,143 | 451,759 | 1,191,001 | 1,871,573 | 13,101,011 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -5,867 | -41,069 | -64,537 | -170,143 | -451,759 | -1,191,001 | -1,871,573 | -13,101,011 |
