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 12,701,585, 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 | 12,701,585 | |
| -1 | -12,701,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,701,585.
Example:
1 x 12,701,585 = 12,701,585
and
-1 x -12,701,585 = 12,701,585
Notice both answers equal 12,701,585
With that explanation out of the way, let's continue. Next, we take the number 12,701,585 and divide it by 2:
12,701,585 ÷ 2 = 6,350,792.5
If the quotient is a whole number, then 2 and 6,350,792.5 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 | 12,701,585 | |
| -1 | -12,701,585 |
Now, we try dividing 12,701,585 by 3:
12,701,585 ÷ 3 = 4,233,861.6667
If the quotient is a whole number, then 3 and 4,233,861.6667 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 | 12,701,585 | |
| -1 | -12,701,585 |
Let's try dividing by 4:
12,701,585 ÷ 4 = 3,175,396.25
If the quotient is a whole number, then 4 and 3,175,396.25 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 | 12,701,585 | |
| -1 | 12,701,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 263 | 743 | 1,315 | 3,419 | 3,715 | 9,659 | 17,095 | 48,295 | 195,409 | 977,045 | 2,540,317 | 12,701,585 |
| -1 | -5 | -13 | -65 | -263 | -743 | -1,315 | -3,419 | -3,715 | -9,659 | -17,095 | -48,295 | -195,409 | -977,045 | -2,540,317 | -12,701,585 |
