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 124,423,013, 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 | 124,423,013 | |
| -1 | -124,423,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,423,013.
Example:
1 x 124,423,013 = 124,423,013
and
-1 x -124,423,013 = 124,423,013
Notice both answers equal 124,423,013
With that explanation out of the way, let's continue. Next, we take the number 124,423,013 and divide it by 2:
124,423,013 ÷ 2 = 62,211,506.5
If the quotient is a whole number, then 2 and 62,211,506.5 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 | 124,423,013 | |
| -1 | -124,423,013 |
Now, we try dividing 124,423,013 by 3:
124,423,013 ÷ 3 = 41,474,337.6667
If the quotient is a whole number, then 3 and 41,474,337.6667 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 | 124,423,013 | |
| -1 | -124,423,013 |
Let's try dividing by 4:
124,423,013 ÷ 4 = 31,105,753.25
If the quotient is a whole number, then 4 and 31,105,753.25 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 | 124,423,013 | |
| -1 | 124,423,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 227 | 2,497 | 2,951 | 3,833 | 32,461 | 42,163 | 49,829 | 548,119 | 870,091 | 9,571,001 | 11,311,183 | 124,423,013 |
| -1 | -11 | -13 | -143 | -227 | -2,497 | -2,951 | -3,833 | -32,461 | -42,163 | -49,829 | -548,119 | -870,091 | -9,571,001 | -11,311,183 | -124,423,013 |
