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 124,001,315, 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 | 124,001,315 | |
| -1 | -124,001,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,001,315.
Example:
1 x 124,001,315 = 124,001,315
and
-1 x -124,001,315 = 124,001,315
Notice both answers equal 124,001,315
With that explanation out of the way, let's continue. Next, we take the number 124,001,315 and divide it by 2:
124,001,315 ÷ 2 = 62,000,657.5
If the quotient is a whole number, then 2 and 62,000,657.5 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 | 124,001,315 | |
| -1 | -124,001,315 |
Now, we try dividing 124,001,315 by 3:
124,001,315 ÷ 3 = 41,333,771.6667
If the quotient is a whole number, then 3 and 41,333,771.6667 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 | 124,001,315 | |
| -1 | -124,001,315 |
Let's try dividing by 4:
124,001,315 ÷ 4 = 31,000,328.75
If the quotient is a whole number, then 4 and 31,000,328.75 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 | 124,001,315 | |
| -1 | 124,001,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 76,781 | 383,905 | 1,305,277 | 1,458,839 | 6,526,385 | 7,294,195 | 24,800,263 | 124,001,315 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -76,781 | -383,905 | -1,305,277 | -1,458,839 | -6,526,385 | -7,294,195 | -24,800,263 | -124,001,315 |
