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 124,046,015, 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 | 124,046,015 | |
| -1 | -124,046,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,046,015.
Example:
1 x 124,046,015 = 124,046,015
and
-1 x -124,046,015 = 124,046,015
Notice both answers equal 124,046,015
With that explanation out of the way, let's continue. Next, we take the number 124,046,015 and divide it by 2:
124,046,015 ÷ 2 = 62,023,007.5
If the quotient is a whole number, then 2 and 62,023,007.5 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 | 124,046,015 | |
| -1 | -124,046,015 |
Now, we try dividing 124,046,015 by 3:
124,046,015 ÷ 3 = 41,348,671.6667
If the quotient is a whole number, then 3 and 41,348,671.6667 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 | 124,046,015 | |
| -1 | -124,046,015 |
Let's try dividing by 4:
124,046,015 ÷ 4 = 31,011,503.75
If the quotient is a whole number, then 4 and 31,011,503.75 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 | 124,046,015 | |
| -1 | 124,046,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 851 | 4,255 | 29,153 | 145,765 | 670,519 | 1,078,661 | 3,352,595 | 5,393,305 | 24,809,203 | 124,046,015 |
| -1 | -5 | -23 | -37 | -115 | -185 | -851 | -4,255 | -29,153 | -145,765 | -670,519 | -1,078,661 | -3,352,595 | -5,393,305 | -24,809,203 | -124,046,015 |
