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 124,564,715, 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 | 124,564,715 | |
| -1 | -124,564,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,564,715.
Example:
1 x 124,564,715 = 124,564,715
and
-1 x -124,564,715 = 124,564,715
Notice both answers equal 124,564,715
With that explanation out of the way, let's continue. Next, we take the number 124,564,715 and divide it by 2:
124,564,715 ÷ 2 = 62,282,357.5
If the quotient is a whole number, then 2 and 62,282,357.5 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 | 124,564,715 | |
| -1 | -124,564,715 |
Now, we try dividing 124,564,715 by 3:
124,564,715 ÷ 3 = 41,521,571.6667
If the quotient is a whole number, then 3 and 41,521,571.6667 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 | 124,564,715 | |
| -1 | -124,564,715 |
Let's try dividing by 4:
124,564,715 ÷ 4 = 31,141,178.75
If the quotient is a whole number, then 4 and 31,141,178.75 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 | 124,564,715 | |
| -1 | 124,564,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 841 | 1,595 | 2,693 | 4,205 | 9,251 | 13,465 | 29,623 | 46,255 | 78,097 | 148,115 | 390,485 | 859,067 | 2,264,813 | 4,295,335 | 11,324,065 | 24,912,943 | 124,564,715 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -841 | -1,595 | -2,693 | -4,205 | -9,251 | -13,465 | -29,623 | -46,255 | -78,097 | -148,115 | -390,485 | -859,067 | -2,264,813 | -4,295,335 | -11,324,065 | -24,912,943 | -124,564,715 |
