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 13,349,063, 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 | 13,349,063 | |
| -1 | -13,349,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,349,063.
Example:
1 x 13,349,063 = 13,349,063
and
-1 x -13,349,063 = 13,349,063
Notice both answers equal 13,349,063
With that explanation out of the way, let's continue. Next, we take the number 13,349,063 and divide it by 2:
13,349,063 ÷ 2 = 6,674,531.5
If the quotient is a whole number, then 2 and 6,674,531.5 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 | 13,349,063 | |
| -1 | -13,349,063 |
Now, we try dividing 13,349,063 by 3:
13,349,063 ÷ 3 = 4,449,687.6667
If the quotient is a whole number, then 3 and 4,449,687.6667 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 | 13,349,063 | |
| -1 | -13,349,063 |
Let's try dividing by 4:
13,349,063 ÷ 4 = 3,337,265.75
If the quotient is a whole number, then 4 and 3,337,265.75 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 | 13,349,063 | |
| -1 | 13,349,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 8,629 | 60,403 | 112,177 | 146,693 | 785,239 | 1,026,851 | 1,907,009 | 13,349,063 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -8,629 | -60,403 | -112,177 | -146,693 | -785,239 | -1,026,851 | -1,907,009 | -13,349,063 |
