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 124,407,101, 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 | 124,407,101 | |
| -1 | -124,407,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,407,101.
Example:
1 x 124,407,101 = 124,407,101
and
-1 x -124,407,101 = 124,407,101
Notice both answers equal 124,407,101
With that explanation out of the way, let's continue. Next, we take the number 124,407,101 and divide it by 2:
124,407,101 ÷ 2 = 62,203,550.5
If the quotient is a whole number, then 2 and 62,203,550.5 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 | 124,407,101 | |
| -1 | -124,407,101 |
Now, we try dividing 124,407,101 by 3:
124,407,101 ÷ 3 = 41,469,033.6667
If the quotient is a whole number, then 3 and 41,469,033.6667 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 | 124,407,101 | |
| -1 | -124,407,101 |
Let's try dividing by 4:
124,407,101 ÷ 4 = 31,101,775.25
If the quotient is a whole number, then 4 and 31,101,775.25 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 | 124,407,101 | |
| -1 | 124,407,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 647 | 2,113 | 4,529 | 8,411 | 14,791 | 27,469 | 58,877 | 192,283 | 1,367,111 | 9,569,777 | 17,772,443 | 124,407,101 |
| -1 | -7 | -13 | -91 | -647 | -2,113 | -4,529 | -8,411 | -14,791 | -27,469 | -58,877 | -192,283 | -1,367,111 | -9,569,777 | -17,772,443 | -124,407,101 |
