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 124,541,219, 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 | 124,541,219 | |
| -1 | -124,541,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,541,219.
Example:
1 x 124,541,219 = 124,541,219
and
-1 x -124,541,219 = 124,541,219
Notice both answers equal 124,541,219
With that explanation out of the way, let's continue. Next, we take the number 124,541,219 and divide it by 2:
124,541,219 ÷ 2 = 62,270,609.5
If the quotient is a whole number, then 2 and 62,270,609.5 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 | 124,541,219 | |
| -1 | -124,541,219 |
Now, we try dividing 124,541,219 by 3:
124,541,219 ÷ 3 = 41,513,739.6667
If the quotient is a whole number, then 3 and 41,513,739.6667 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 | 124,541,219 | |
| -1 | -124,541,219 |
Let's try dividing by 4:
124,541,219 ÷ 4 = 31,135,304.75
If the quotient is a whole number, then 4 and 31,135,304.75 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 | 124,541,219 | |
| -1 | 124,541,219 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 179 | 209 | 1,969 | 3,329 | 3,401 | 36,619 | 37,411 | 63,251 | 595,891 | 695,761 | 6,554,801 | 11,321,929 | 124,541,219 |
| -1 | -11 | -19 | -179 | -209 | -1,969 | -3,329 | -3,401 | -36,619 | -37,411 | -63,251 | -595,891 | -695,761 | -6,554,801 | -11,321,929 | -124,541,219 |
