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 124,334,413, 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 | 124,334,413 | |
| -1 | -124,334,413 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,334,413.
Example:
1 x 124,334,413 = 124,334,413
and
-1 x -124,334,413 = 124,334,413
Notice both answers equal 124,334,413
With that explanation out of the way, let's continue. Next, we take the number 124,334,413 and divide it by 2:
124,334,413 ÷ 2 = 62,167,206.5
If the quotient is a whole number, then 2 and 62,167,206.5 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 | 124,334,413 | |
| -1 | -124,334,413 |
Now, we try dividing 124,334,413 by 3:
124,334,413 ÷ 3 = 41,444,804.3333
If the quotient is a whole number, then 3 and 41,444,804.3333 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 | 124,334,413 | |
| -1 | -124,334,413 |
Let's try dividing by 4:
124,334,413 ÷ 4 = 31,083,603.25
If the quotient is a whole number, then 4 and 31,083,603.25 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 | 124,334,413 | |
| -1 | 124,334,413 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 343 | 833 | 5,831 | 21,323 | 149,261 | 362,491 | 1,044,827 | 2,537,437 | 7,313,789 | 17,762,059 | 124,334,413 |
| -1 | -7 | -17 | -49 | -119 | -343 | -833 | -5,831 | -21,323 | -149,261 | -362,491 | -1,044,827 | -2,537,437 | -7,313,789 | -17,762,059 | -124,334,413 |
