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 13,523,585, 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 | 13,523,585 | |
| -1 | -13,523,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,523,585.
Example:
1 x 13,523,585 = 13,523,585
and
-1 x -13,523,585 = 13,523,585
Notice both answers equal 13,523,585
With that explanation out of the way, let's continue. Next, we take the number 13,523,585 and divide it by 2:
13,523,585 ÷ 2 = 6,761,792.5
If the quotient is a whole number, then 2 and 6,761,792.5 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 | 13,523,585 | |
| -1 | -13,523,585 |
Now, we try dividing 13,523,585 by 3:
13,523,585 ÷ 3 = 4,507,861.6667
If the quotient is a whole number, then 3 and 4,507,861.6667 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 | 13,523,585 | |
| -1 | -13,523,585 |
Let's try dividing by 4:
13,523,585 ÷ 4 = 3,380,896.25
If the quotient is a whole number, then 4 and 3,380,896.25 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 | 13,523,585 | |
| -1 | 13,523,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 389 | 409 | 1,945 | 2,045 | 6,613 | 6,953 | 33,065 | 34,765 | 159,101 | 795,505 | 2,704,717 | 13,523,585 |
| -1 | -5 | -17 | -85 | -389 | -409 | -1,945 | -2,045 | -6,613 | -6,953 | -33,065 | -34,765 | -159,101 | -795,505 | -2,704,717 | -13,523,585 |
