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 29,684,039, 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 | 29,684,039 | |
| -1 | -29,684,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,684,039.
Example:
1 x 29,684,039 = 29,684,039
and
-1 x -29,684,039 = 29,684,039
Notice both answers equal 29,684,039
With that explanation out of the way, let's continue. Next, we take the number 29,684,039 and divide it by 2:
29,684,039 ÷ 2 = 14,842,019.5
If the quotient is a whole number, then 2 and 14,842,019.5 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 | 29,684,039 | |
| -1 | -29,684,039 |
Now, we try dividing 29,684,039 by 3:
29,684,039 ÷ 3 = 9,894,679.6667
If the quotient is a whole number, then 3 and 9,894,679.6667 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 | 29,684,039 | |
| -1 | -29,684,039 |
Let's try dividing by 4:
29,684,039 ÷ 4 = 7,421,009.75
If the quotient is a whole number, then 4 and 7,421,009.75 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 | 29,684,039 | |
| -1 | 29,684,039 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 239 | 1,613 | 1,673 | 2,629 | 11,291 | 17,743 | 18,403 | 124,201 | 385,507 | 2,698,549 | 4,240,577 | 29,684,039 |
| -1 | -7 | -11 | -77 | -239 | -1,613 | -1,673 | -2,629 | -11,291 | -17,743 | -18,403 | -124,201 | -385,507 | -2,698,549 | -4,240,577 | -29,684,039 |
