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 28,835,585, 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 | 28,835,585 | |
| -1 | -28,835,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,835,585.
Example:
1 x 28,835,585 = 28,835,585
and
-1 x -28,835,585 = 28,835,585
Notice both answers equal 28,835,585
With that explanation out of the way, let's continue. Next, we take the number 28,835,585 and divide it by 2:
28,835,585 ÷ 2 = 14,417,792.5
If the quotient is a whole number, then 2 and 14,417,792.5 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 | 28,835,585 | |
| -1 | -28,835,585 |
Now, we try dividing 28,835,585 by 3:
28,835,585 ÷ 3 = 9,611,861.6667
If the quotient is a whole number, then 3 and 9,611,861.6667 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 | 28,835,585 | |
| -1 | -28,835,585 |
Let's try dividing by 4:
28,835,585 ÷ 4 = 7,208,896.25
If the quotient is a whole number, then 4 and 7,208,896.25 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 | 28,835,585 | |
| -1 | 28,835,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 71 | 215 | 355 | 1,889 | 3,053 | 9,445 | 15,265 | 81,227 | 134,119 | 406,135 | 670,595 | 5,767,117 | 28,835,585 |
| -1 | -5 | -43 | -71 | -215 | -355 | -1,889 | -3,053 | -9,445 | -15,265 | -81,227 | -134,119 | -406,135 | -670,595 | -5,767,117 | -28,835,585 |
