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 13,663,013, 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 | 13,663,013 | |
| -1 | -13,663,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,663,013.
Example:
1 x 13,663,013 = 13,663,013
and
-1 x -13,663,013 = 13,663,013
Notice both answers equal 13,663,013
With that explanation out of the way, let's continue. Next, we take the number 13,663,013 and divide it by 2:
13,663,013 ÷ 2 = 6,831,506.5
If the quotient is a whole number, then 2 and 6,831,506.5 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 | 13,663,013 | |
| -1 | -13,663,013 |
Now, we try dividing 13,663,013 by 3:
13,663,013 ÷ 3 = 4,554,337.6667
If the quotient is a whole number, then 3 and 4,554,337.6667 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 | 13,663,013 | |
| -1 | -13,663,013 |
Let's try dividing by 4:
13,663,013 ÷ 4 = 3,415,753.25
If the quotient is a whole number, then 4 and 3,415,753.25 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 | 13,663,013 | |
| -1 | 13,663,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 89 | 91 | 241 | 623 | 637 | 1,157 | 1,687 | 3,133 | 4,361 | 8,099 | 11,809 | 21,449 | 21,931 | 56,693 | 150,143 | 153,517 | 278,837 | 1,051,001 | 1,951,859 | 13,663,013 |
| -1 | -7 | -13 | -49 | -89 | -91 | -241 | -623 | -637 | -1,157 | -1,687 | -3,133 | -4,361 | -8,099 | -11,809 | -21,449 | -21,931 | -56,693 | -150,143 | -153,517 | -278,837 | -1,051,001 | -1,951,859 | -13,663,013 |
