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 13,000,949, 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 | 13,000,949 | |
| -1 | -13,000,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,000,949.
Example:
1 x 13,000,949 = 13,000,949
and
-1 x -13,000,949 = 13,000,949
Notice both answers equal 13,000,949
With that explanation out of the way, let's continue. Next, we take the number 13,000,949 and divide it by 2:
13,000,949 ÷ 2 = 6,500,474.5
If the quotient is a whole number, then 2 and 6,500,474.5 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 | 13,000,949 | |
| -1 | -13,000,949 |
Now, we try dividing 13,000,949 by 3:
13,000,949 ÷ 3 = 4,333,649.6667
If the quotient is a whole number, then 3 and 4,333,649.6667 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 | 13,000,949 | |
| -1 | -13,000,949 |
Let's try dividing by 4:
13,000,949 ÷ 4 = 3,250,237.25
If the quotient is a whole number, then 4 and 3,250,237.25 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 | 13,000,949 | |
| -1 | 13,000,949 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 151 | 179 | 481 | 1,963 | 2,327 | 5,587 | 6,623 | 27,029 | 72,631 | 86,099 | 351,377 | 1,000,073 | 13,000,949 |
| -1 | -13 | -37 | -151 | -179 | -481 | -1,963 | -2,327 | -5,587 | -6,623 | -27,029 | -72,631 | -86,099 | -351,377 | -1,000,073 | -13,000,949 |
