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 134,014,415, 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 | 134,014,415 | |
| -1 | -134,014,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,014,415.
Example:
1 x 134,014,415 = 134,014,415
and
-1 x -134,014,415 = 134,014,415
Notice both answers equal 134,014,415
With that explanation out of the way, let's continue. Next, we take the number 134,014,415 and divide it by 2:
134,014,415 ÷ 2 = 67,007,207.5
If the quotient is a whole number, then 2 and 67,007,207.5 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 | 134,014,415 | |
| -1 | -134,014,415 |
Now, we try dividing 134,014,415 by 3:
134,014,415 ÷ 3 = 44,671,471.6667
If the quotient is a whole number, then 3 and 44,671,471.6667 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 | 134,014,415 | |
| -1 | -134,014,415 |
Let's try dividing by 4:
134,014,415 ÷ 4 = 33,503,603.75
If the quotient is a whole number, then 4 and 33,503,603.75 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 | 134,014,415 | |
| -1 | 134,014,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 157 | 395 | 785 | 2,161 | 10,805 | 12,403 | 62,015 | 170,719 | 339,277 | 853,595 | 1,696,385 | 26,802,883 | 134,014,415 |
| -1 | -5 | -79 | -157 | -395 | -785 | -2,161 | -10,805 | -12,403 | -62,015 | -170,719 | -339,277 | -853,595 | -1,696,385 | -26,802,883 | -134,014,415 |
