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 124,333,253, 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 | 124,333,253 | |
| -1 | -124,333,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,333,253.
Example:
1 x 124,333,253 = 124,333,253
and
-1 x -124,333,253 = 124,333,253
Notice both answers equal 124,333,253
With that explanation out of the way, let's continue. Next, we take the number 124,333,253 and divide it by 2:
124,333,253 ÷ 2 = 62,166,626.5
If the quotient is a whole number, then 2 and 62,166,626.5 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 | 124,333,253 | |
| -1 | -124,333,253 |
Now, we try dividing 124,333,253 by 3:
124,333,253 ÷ 3 = 41,444,417.6667
If the quotient is a whole number, then 3 and 41,444,417.6667 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 | 124,333,253 | |
| -1 | -124,333,253 |
Let's try dividing by 4:
124,333,253 ÷ 4 = 31,083,313.25
If the quotient is a whole number, then 4 and 31,083,313.25 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 | 124,333,253 | |
| -1 | 124,333,253 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 83 | 473 | 913 | 3,167 | 3,569 | 34,837 | 39,259 | 136,181 | 262,861 | 1,497,991 | 2,891,471 | 11,303,023 | 124,333,253 |
| -1 | -11 | -43 | -83 | -473 | -913 | -3,167 | -3,569 | -34,837 | -39,259 | -136,181 | -262,861 | -1,497,991 | -2,891,471 | -11,303,023 | -124,333,253 |
