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 134,404,309, 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 | 134,404,309 | |
| -1 | -134,404,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,404,309.
Example:
1 x 134,404,309 = 134,404,309
and
-1 x -134,404,309 = 134,404,309
Notice both answers equal 134,404,309
With that explanation out of the way, let's continue. Next, we take the number 134,404,309 and divide it by 2:
134,404,309 ÷ 2 = 67,202,154.5
If the quotient is a whole number, then 2 and 67,202,154.5 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 | 134,404,309 | |
| -1 | -134,404,309 |
Now, we try dividing 134,404,309 by 3:
134,404,309 ÷ 3 = 44,801,436.3333
If the quotient is a whole number, then 3 and 44,801,436.3333 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 | 134,404,309 | |
| -1 | -134,404,309 |
Let's try dividing by 4:
134,404,309 ÷ 4 = 33,601,077.25
If the quotient is a whole number, then 4 and 33,601,077.25 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 | 134,404,309 | |
| -1 | 134,404,309 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 263 | 2,069 | 3,419 | 4,997 | 26,897 | 39,311 | 64,961 | 511,043 | 544,147 | 7,073,911 | 10,338,793 | 134,404,309 |
| -1 | -13 | -19 | -247 | -263 | -2,069 | -3,419 | -4,997 | -26,897 | -39,311 | -64,961 | -511,043 | -544,147 | -7,073,911 | -10,338,793 | -134,404,309 |
