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 29,284,589, 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 | 29,284,589 | |
| -1 | -29,284,589 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,284,589.
Example:
1 x 29,284,589 = 29,284,589
and
-1 x -29,284,589 = 29,284,589
Notice both answers equal 29,284,589
With that explanation out of the way, let's continue. Next, we take the number 29,284,589 and divide it by 2:
29,284,589 ÷ 2 = 14,642,294.5
If the quotient is a whole number, then 2 and 14,642,294.5 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 | 29,284,589 | |
| -1 | -29,284,589 |
Now, we try dividing 29,284,589 by 3:
29,284,589 ÷ 3 = 9,761,529.6667
If the quotient is a whole number, then 3 and 9,761,529.6667 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 | 29,284,589 | |
| -1 | -29,284,589 |
Let's try dividing by 4:
29,284,589 ÷ 4 = 7,321,147.25
If the quotient is a whole number, then 4 and 7,321,147.25 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 | 29,284,589 | |
| -1 | 29,284,589 |
If you did it right, you will end up with this table:
| 1 | 23 | 71 | 79 | 227 | 1,633 | 1,817 | 5,221 | 5,609 | 16,117 | 17,933 | 129,007 | 370,691 | 412,459 | 1,273,243 | 29,284,589 |
| -1 | -23 | -71 | -79 | -227 | -1,633 | -1,817 | -5,221 | -5,609 | -16,117 | -17,933 | -129,007 | -370,691 | -412,459 | -1,273,243 | -29,284,589 |
