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 29,003,915, 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 | 29,003,915 | |
| -1 | -29,003,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,003,915.
Example:
1 x 29,003,915 = 29,003,915
and
-1 x -29,003,915 = 29,003,915
Notice both answers equal 29,003,915
With that explanation out of the way, let's continue. Next, we take the number 29,003,915 and divide it by 2:
29,003,915 ÷ 2 = 14,501,957.5
If the quotient is a whole number, then 2 and 14,501,957.5 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 | 29,003,915 | |
| -1 | -29,003,915 |
Now, we try dividing 29,003,915 by 3:
29,003,915 ÷ 3 = 9,667,971.6667
If the quotient is a whole number, then 3 and 9,667,971.6667 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 | 29,003,915 | |
| -1 | -29,003,915 |
Let's try dividing by 4:
29,003,915 ÷ 4 = 7,250,978.75
If the quotient is a whole number, then 4 and 7,250,978.75 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 | 29,003,915 | |
| -1 | 29,003,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 317 | 631 | 1,585 | 3,155 | 9,193 | 18,299 | 45,965 | 91,495 | 200,027 | 1,000,135 | 5,800,783 | 29,003,915 |
| -1 | -5 | -29 | -145 | -317 | -631 | -1,585 | -3,155 | -9,193 | -18,299 | -45,965 | -91,495 | -200,027 | -1,000,135 | -5,800,783 | -29,003,915 |
