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 124,003,729, 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 | 124,003,729 | |
| -1 | -124,003,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,003,729.
Example:
1 x 124,003,729 = 124,003,729
and
-1 x -124,003,729 = 124,003,729
Notice both answers equal 124,003,729
With that explanation out of the way, let's continue. Next, we take the number 124,003,729 and divide it by 2:
124,003,729 ÷ 2 = 62,001,864.5
If the quotient is a whole number, then 2 and 62,001,864.5 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 | 124,003,729 | |
| -1 | -124,003,729 |
Now, we try dividing 124,003,729 by 3:
124,003,729 ÷ 3 = 41,334,576.3333
If the quotient is a whole number, then 3 and 41,334,576.3333 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 | 124,003,729 | |
| -1 | -124,003,729 |
Let's try dividing by 4:
124,003,729 ÷ 4 = 31,000,932.25
If the quotient is a whole number, then 4 and 31,000,932.25 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 | 124,003,729 | |
| -1 | 124,003,729 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 229 | 601 | 901 | 3,893 | 10,217 | 12,137 | 31,853 | 137,629 | 206,329 | 541,501 | 2,339,693 | 7,294,337 | 124,003,729 |
| -1 | -17 | -53 | -229 | -601 | -901 | -3,893 | -10,217 | -12,137 | -31,853 | -137,629 | -206,329 | -541,501 | -2,339,693 | -7,294,337 | -124,003,729 |
