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 29,127,439, 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 | 29,127,439 | |
| -1 | -29,127,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,127,439.
Example:
1 x 29,127,439 = 29,127,439
and
-1 x -29,127,439 = 29,127,439
Notice both answers equal 29,127,439
With that explanation out of the way, let's continue. Next, we take the number 29,127,439 and divide it by 2:
29,127,439 ÷ 2 = 14,563,719.5
If the quotient is a whole number, then 2 and 14,563,719.5 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 | 29,127,439 | |
| -1 | -29,127,439 |
Now, we try dividing 29,127,439 by 3:
29,127,439 ÷ 3 = 9,709,146.3333
If the quotient is a whole number, then 3 and 9,709,146.3333 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 | 29,127,439 | |
| -1 | -29,127,439 |
Let's try dividing by 4:
29,127,439 ÷ 4 = 7,281,859.75
If the quotient is a whole number, then 4 and 7,281,859.75 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 | 29,127,439 | |
| -1 | 29,127,439 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 83 | 523 | 671 | 913 | 5,063 | 5,753 | 31,903 | 43,409 | 55,693 | 350,933 | 477,499 | 2,647,949 | 29,127,439 |
| -1 | -11 | -61 | -83 | -523 | -671 | -913 | -5,063 | -5,753 | -31,903 | -43,409 | -55,693 | -350,933 | -477,499 | -2,647,949 | -29,127,439 |
